The moment America clutched a killer to its breast: Terrorist wife pictured as she presented herself at immigration in the country she hated - 16 months before she and husband gunned down 14

• e-mail

A new image has emerged showing the San Bernardino husband-and-wife terrorist duo as dour newlyweds entering the US upon their arrival from Saudi Arabia last year - as the FBI revealed that both shooters were radicalized.

The image, first obtained by ABC News Monday morning, was apparently taken as Syed Farook and his bride, Tashfeen Malik, were going through customs in Chicago's O'Hare International Airport on the evening of July 27, 2014.

It marks the first time that the couple responsible for killing 14 people and injuring 21 others during a holiday party held at the Inland Regional Center in San Bernardino, California, on December 2 are seen posing together.

Welcome to America: This image shows San Bernardino shooters Tashfeen Malik and Syed Farook going through customs as O'Hare Airport in Chicago last July upon their arrival from Saudi Arabia

The photograph depicts Ms Malik, 29, dressed in a black hijab on her head and what appears to be a matching dress, staring stone-faced straight into the camera in her first moments on US soil.

Farook, 28, wearing a loose light-colored shirt and a skull cap, stands a few paces behind his partner.

The future San Bernardino gunman is sporting a beard but no mustache in the photo. The couple are wearing blank expressions in the photo.

At a press conference held Monday afternoon, David Bowdich, assistant director of the FBI's Los Angeles office, said the bureau now believes both Farook and Malik were radicalized and had been 'for some time,'  taking target practice at ranges in the Los Angeles area. He added that investigators do know know at this time when or how they were radicalized.

Malik and Farook reportedly met on a Muslim dating website sometime in 2013. They came face-to-face for the first time in Saudi Arabia in July 2014 when Farook took a two-week vacation to meet his bride-to-be and her family. 

Investigators with the FBI previously revealed that Malik entered the US on a K-1 fiancee visa and married Farook in California a month later. The wedding in Riverside may have been preceded by an earlier religious ceremony in Saudi Arabia, according to some officials.

In late May of this year, the newlyweds welcomed their baby daughter, who is now 6 months old and an orphan after Malik and Farook were killed in a gun battle with police just hours after the Wednesday morning shooting rampage.

Witnesses who were inside the conference room at the Inland Regional Center where the attack took place described for ABC what went down inside the venue when Farook and Malik opened fire. 

The witnesses estimated that the room had about eight tables, with eight people at each as well as a table in the front where the supervisors sat. 

Farook had attended the party but left abruptly, returning at 11am with his wife in tow and armed with assault rifles and handguns. 

The couple entered the room from the left and then opened fire, and one of the first tables targeted was the table where Farook had been sitting earlier in the day. 

The couple's gunfire blew out the windows in the room and at least one of the survivors jumped through the shattered glass to safety. Others sought shelter in the bathrooms.  

Newly released dispatch tapes showed police had the name of one of the California shooting suspects as officers swarmed the scene of the massacre.

Recordings posted by The Press-Enterprise newspaper include an officer saying Syed Farook was a possible suspect. The officer says Farook seemed nervous when he left the building in San Bernardino before the attack and he matched the description of a shooter.

Witnesses told officers that two gunmen were wearing ski-type masks and vests.

The tapes reveal the back-and-forth between officers in the field and calm-talking dispatchers. 

At a press conference held Monday morning, Dr Dev GnanaDev, chief of surgery at Arrowhead Regional Medical Center in San Bernardino, California, described Wednesday's deadly rampage that claimed 14 innocent lives as one of the most horrific disasters in his 35-year career.

'What really bothers me most is that none of the 14 who perished had a chance,' a somber Dr GnanaDev told reporters.

Also on Monday, ABC News released what is believed to be the first recording featuring the 28-year-old gunman's voice.

Farook, who was born in Illinois to Pakistani parents, is heard stating his full name, 'Syed Farook,' in a clear voice, without any audible accent, in a voicemail greeting.

The release of the first known photo of the terrorist duo comes as federal officials continue to delve into Malik and Farook's biographies in an effort to trace their path to radicalization, and learn what contacts the woman might have had with Islamic militants in Pakistan and Saudi Arabia, where she grew up.

It was revealed on Friday that Malik pledged allegiance to ISIS on Facebook just minutes into the deadly attack.

A news agency affiliated with the extremist group later described the married couple as supporters of ISIS, but stopped short of claiming responsibility for the massacre in California. 

An official said on condition of anonymity that authorities still lack clear evidence that the wife was radicalized overseas or that she in turn radicalized her husband, though they are actively investigating that.

The FBI announced on Friday that based on existing evidence, including a massive stockpile of pipe bombs and ammunition in the couple's Redlands, California, home, the shooting rampage was being investigated as an act of terror. 

It was also revealed that in the days leading up to the massacre, Farook made two trips to a gun range in Riverside, law enforcement sources confirmed to Fox News on Sunday.

According to the sources, the shooter spent time at the Riverside Magnum Shooting Range on November 29 and November 30, firing an AR-15 and a handgun, which he brought with him.

Federal investigators also believe that both Malik and Farook were 'dry-firing,' or pulling the trigger on an unloaded weapon, in the backyard of a home in the run-up to the attack.

Malik's estranged relatives in Pakistan have said she appeared to have abandoned the family's moderate Islam and become more radicalized in Saudi Arabia, where she moved as a toddler.

She returned to Pakistan and studied pharmacy at Bahauddin Zakaria University in Multan from 2007 to 2012.

While in Multan, she also attended a religious school, which Pakistani intelligence officials on Monday identified it as the Al-Huda International Seminary. The school is a women-only madrassa with a chain across Pakistan and branches in the U.S. and Canada, said the officials, speaking on condition of anonymity in line with regulations.

Malik spent more than a year at Al-Huda, taking classes six days a week, the school's spokeswoman Farrukh Chaudhry told The Associated Press.

She enrolled in a two-year course to learn the Muslim holy book, Quran, its translation and interpretation but did not finish the course, Chaudhry added. Malik was a student there from April 17, 2013 until May 3, 2014, when she handed in her last paper in the first-year curriculum, the spokeswoman said. 

'There's a serious investigation ongoing into what she was doing in Pakistan and in Saudi,' US Representative Michael McCaul said on Fox News Sunday. 'We think that she had a lot to do with the radicalization process and perhaps with Mr. Farook's radicalization from within the United States.

'The wild card here is the wife Malik,' said McCaul, the Republican chairman of the House Homeland Security Committee. He said investigators were also looking at where they got the money to acquire the guns.

US Attorney General Loretta Lynch said US authorities have no evidence that the shooters were part of a larger terrorism cell but were working with their counterparts overseas to gather information about their lives.

Tributes: Flowers, balloons, notes and flags have been placed near the site of Wednesday's attacks where 14 were killed and 21 injured

Remembered: Touching notes and tributes have been left to the victims of Syed Rizwan Farook and Tashfeen Malik's terror attack which killed 14 and injured 21

'We are trying to learn everything we can about both of these individuals,' Lynch said on NBC's Meet the Press. 'It will be a long process, it will be an exhaustive process.

'And we are trying to learn as much as we can about her life before they met, after they met and frankly, after she came here as well. What we are trying to focus on again is what motivated these two individuals.'

McCaul said it was unclear what ties the couple had with the Islamic State, which has said the pair were 'followers.' At a minimum, he said, the militant group inspired the attack. Malik is believed to have pledged allegiance to the group in a Facebook posting shortly before the shooting.

Officials have acknowledged they had no information about the couple before the killing other than routine matters related to Malik's immigration status in the United States.

Chaz Harrison, a colleague of Farook's who had known him since college, told CBS News that the Illinois native of Pakistani descent 'didn't want to be in the United States' because 'being in this country didn't fit his views.'

Harrison described Farook as 'passionate about his religion' and said he did not feel he could practice it the way he wanted to in the US.

The 28-year-old with a $70,000-a-year-old job as a county environmental health inspector also had misgivings about paying taxes because he was concerned his money was supporting America’s war and Islam and Muslims, according to Harrison.

Final stand: Farook and Malik were both killed during a gun battle with police after the San Bernardino shooting. Pictured here is an officer looking at evidence near the couple's bullet-riddled SUV 

Practice: Officials say Farook visited a gun range in the days leading up to the attack, firing an AR-15 and a handgun, which would later be used to kill 14 people and injure 21 others

Under scrutiny: The FBI is investigating how much Farook’s mother, Rafia Sultana Farook (left), 62, knew about the impending attack. Rafia lived in the same home in Redlands, California, as her son (right) and his wife

Under scrutiny: Farook's 66-year-old father, a naturalized US citizen also named Syed Farook (pictured December 7 in Riverside), has been placed on a terror watch list 

The colleague added that Farook once confided in him that he had made plans to move to Dubai but could not find a job there.

Unlike other co-workers of Farook's at the San Bernardino Department of Health who characterized him as exceedingly shy and reserved, Harrison said he was a 'talker' who could go on for hours about cars and religion.

But whenever the conversation turned to his newlywed wife, Tashfeen Malik, Harrison said Farook would clam up and turn 'secretive.'

‘One of the first things I said, “Hey you got a picture?” He didn't have any pictures,’ Harrison told the news agency. ‘He said that she was very uncomfortable. Everyone looked at her -- they stared her because of the way she dressed.’ 

In the wake of the attack, Syed Farook's 66-yer-old father, also named Syed Farook, has been placed on a federal watch list.

An official familiar with the FBI investigation told ABC News that the elder Mr Farook has made multiple lengthy trips to Pakistan, including this and last year. 

Accused: Enrique Marquez, 29, allegedly purchased assault-style weapons for the San Bernardino shooters

Another official said the gunman's' father came to the US in 1972 and became a naturalized citizen in 1999. 

In an interview with an Italian newspaper over the weekend, the elder Syed Farook reportedly said that his son was fascinated with ISIS and hated the State of Israel.

Other family members have since downplayed Ms Farook's remarks, saying he is 'not stable ' and 'not handling this well.' The father himself later said he did not recall talking to the newspaper. 

The FBI is also investigating exactly how much Farook’s mother knew about the impending attack.

Rafia Sultana Farook, 62, lived in the same home in Redlands, California, as her son and his wife built a dozen pipe bombs and stored 6,000 rounds of ammunition.

In a press conference on Friday, attorneys David Chesley and Mohammed Abuershaid, who represent the Farook family, said that Rafia had been extensively questioned by the FBI following the shooting and there was no evidence she had prior knowledge of the attack.

The FBI also intends to speak to Enrique Marquez, 29, Farook's close friend and neighbor, who is accused of purchasing the guns that were used to mow down 14 innocent people.

The two modified 'assault-style' weapons, used by the couple in addition to handguns, were purchased by Marquez three years ago, according to ABC News.

He checked himself into a mental health facility in Long Beach, California, on Wednesday afternoon – hours after the attacks. His home has been raided but he is not considered a suspect in the terror attack.

FROM TERROR ATTACK TO POLITICAL BATTLEGROUND: WHERE OBAMA AND THE PRESIDENTIAL HOPEFULS STAND ON ISIS 

President Barack Obama used a rare live address to reassure Americans that the San Bernardino shootings were an isolated incident and to outline his plans in the ongoing battle against ISIS. 

The President firmly dismissed a change in strategy in the war against the extremists that would require combat troops on the ground in Iraq and Syria. 

And while the terrorist group is made up of 'thugs and killers' and is part of a 'cult of death', he again refused to call them 'radical Islamic terrorists'. 

'Muslim Americans are our friends and our neighbors are coworkers, our sports heroes. And yes, they are our men and women in uniform who are willing to die in defense of our country,' the president said, speaking from the Oval Office. 'We have to remember that.'

President Barack Obama used his Sunday night address on terrorism to assure the American people that the California shootings last week appear to be an isolated incident and urged them to treat followers of Islam with tolerance

He also called on Congress to pass legislation barring individuals on the no-fly list from purchasing guns.

His position was backed by Democrat front-runner Hillary Clinton, who is similarly refusing to refer to Islam when discussing ISIS. 

Speaking to George Stephanopoulos on This Week, she said the term 'radical Islamic terrorism' sounds like we are declaring war against a religion', instead of militants.

Stephanopoulos asked her: 'Isn’t it a mistake not to say it plain? That the violence is being pushed by radical elements in their faith?'

Clinton responded: 'Well that’s another thing. "Radical elements who use a dangerous and distorted view of Islam to promote their jihadist ambitions." I’m fine with that. I say it all the time.'

Pressed further, she added: 'The problem is, that sounds like we are declaring war against a religion. That to me is number one, wrong.

'It doesn't do justice to the vast number of Muslims in our country and around the world who are peaceful people.

'Number two, it helps to create this clash of civilizations that is actually a recruiting tool for ISIS and other radical jihadists who use this as a way of saying, "We are in a war against the West, you must join us."'

She has also called for an 'intensified air campaign' against ISIS overseas but spoke against troops on the ground which would 'make things worse, not better'. 

She also said she wants to 'dismantle the global infrastructure of terror' and particularly called on social media sites to help. 

She wants to 'toughen our defense at home' and also called for fiance visas to be reviewed in light of the San Bernardino attacks - and for those on the no-flight list to be denied the right to buy guns

The Democrat duo's standpoint has, however, been widely ridiculed by those on the other end of the political spectrum 

Donald Trump led the charge, live tweeting throughout Obama's address. 

'Obama refused to say (he just can't say it), that we are at WAR with RADICAL ISLAMIC TERRORISTS,' he wrote.

‘Could you imagine FDR going before Congress and saying, “We were attacked yesterday on Pearl Harbor. I really don’t want to talk about who did it, but you know, we just want to say that they were terrible people and they were thugs,” ’ said Mike Huckabee (pictured) this morning

He subsequently reposted another tweet by a supporter, adding: '[Obama] will never say it, therefore he will never have a solution!'

Mike Huckabee went one step further. 

‘Could you imagine FDR going before Congress and saying, 'We were attacked yesterday on Pearl Harbor. I really don’t want to talk about who did it, but you know, we just want to say that they were terrible people and they were thugs,' the former governor of Arkansas told Fox and Friends. 

‘Well who was it, Mr. President? Well, we don’t want to get into it, because I don’t want you to have any bad feelings toward the Japanese.' 

Ted Cruz also invoked Pearl Harbor in his response to Obama’s address and proclaimed that afterward ‘FDR did not give a partisan speech, rather he called on Americans to unite and 'win through to absolute victory'.

‘If I am elected President, I will direct the Department of Defense to destroy ISIS. And I will shut down the broken immigration system that is letting jihadists into our country,’ the Texas senator said.

And he charged, ‘Nothing President Obama said tonight will assist in either case.’
