PICTURED: The shot-out shell of a home where cop-killer barricaded himself for nearly 21 hours before emerging, guns blazing, and being shot dead by police

• e-mail

The Middletown, Delaware home where a cop-killer barricaded himself for nearly 21 hours now lays in shambles. 

Nearly all of the windows have been broken, the front door blown off its hinges and an entire corner of the home ripped open, while pieces of white siding litter the pristine green lawn.

Suspect Burgon Sealy Jr., 26, retreated to the family home Wednesday afternoon, after reportedly shooting dead state trooper Cpl. Stephen J. Ballard, 32, outside of a Wawa convenience store. 

He managed to keep police at bay throughout the night and into the next morning.

The stand-off finally came to an end around 9:17am, when Sealy emerged and started shooting at officers.

Cops returned his fire and struck Sealy - who was pronounced dead at 9:29am.

So far, there have been no reports of officers being injured in the stand-off

The home where Sealy barricaded himself is registered to his father. Records show Sealy had been arrested in 2013 on gun and drug charges in Orlando, Florida. A childhood friend, Scott Adkins, says Sealy was fond of guns as early as middle school. 

At a Monday afternoon press conference, police relayed what they know so far about the deadly shooting. 

Just after noon on Wednesday, they say Ballard conducted a stop on a car in the parking lot of a Wawa convenience store. Police wouldn't say what the stop was for, but they believe Ballard had reason to stop the red Dodge Charger.  

Shortly after Sealy was pronounced dead, officers rove this piece of equipment from the crime scene

It appears that Sealy tried to shoot the front of the cab of the front-end loader

Both the driver and the passenger of the vehicle, Sealy, produced their ID cards to Ballard. 

Ballard then walked to the other side of the car to talk to Sealy. While speaking, Sealy indicated to Ballard that he had arrived at the Wawa in a grey  Honda. 

A struggle ensued when Ballard then asked Sealy to get out of the car.  

Sealy pulled out a gun and started shooting at Ballard who tried to run for cover behind another car. 

Sealy followed and continued to shoot Ballard several times in the upper body - killing him. 

He then sped off in the grey Honda, while the driver of the red charger stayed until police showed up and was taken into custody. Police say that person has since been released, but that they are still conducting their investigation. 

From there, Sealy returned home and called relatives to tell them what happened. 

Those relatives immediately reported him to police, who responded to Sealy's home in Middletown. They say he was the only resident in the house.

Police say the gunman continued to shoot at officers throughout the night

According to his Facebook profile, Cpl. Ballard appeared to be married 

Sealey, alone in the house, refused to leave and fired several shots at officers surrounding the home. No other officers were injured.

Hostage negotiators were on the scene and established contact with the man in an effort to get him to surrender peacefully. But there was no quick resolution as the standoff stretched into the evening.

Around 6:45pm Wednesday, several loud pops echoed through the neighborhood, as police repeatedly ordered the suspect to come out of the house with his hands up.

Sealy completely stopped talking to officers around 8:22pm, at which point they used an explosive device to blow the door of the house off its hinges. But Sealy still wouldn't come out.  

Officers heard gunfire come from the house around 4am, but Sealy made no moves. Police officers breached numerous windows but again did not enter the residence.

The barricade finally came to an end around 9:17am, when Sealy came out of the house with 'weapons' and started shooting at officers. 

Officers returned fire and struck Sealy. Law enforcement tried to save Sealy's life, but he died from his injuries at 9:29am. 

Authorities investigate the scene of the shooting on Wednesday in Bear, Delaware

 State police superintendent Col. Nathaniel McQueen said Ballard approached a vehicle that had two suspicious people inside at the Wawa

One man got out of the car and shot Ballard several times before running away, McQueen said at a Wednesday afternoon news conference. The other man was arrested at the scene

The trooper was shot shortly after noon outside a Wawa convenience store (the building seen on the right), and police said they had not determined the motive for the attack

The trooper noticed a 'suspicious' car just ouside of the Wawa, which is located on the 1600 block of Pulaski Highway. There were two people inside the vehicle

Sarah Adkins, 18, who lives with her parents on the same street where the suspect was barricaded, said that shortly after arriving home early Thursday afternoon, she started hearing sporadic gunfire that lasted for about an hour and resumed at other intervals. 

'It's been scary,' said Adkins, who was told by police to go to her basement and stay there.

'Just me and my dog,' said Adkins, who spent the day talking on the phone with her friends and family.

'I'm doing OK. My mom is a nervous wreck,' said Adkins, whose parents, along with other residents, have been unable to return to their homes. A local fire company opened its facility to temporarily house evacuated residents while police continued to negotiate with the suspect.

Adkins said the man believed to be the suspect went to school with her brothers, and has always seemed friendly, smiling and waving at her when she last saw him a couple of weeks ago.

Police used a robo-calling system to tell residents in the areas to stay inside and lock their doors. The Appoquinimink School District went on lockdown, keeping all students and staff inside school buildings. They were later allowed to leave as police secured the area.

Ballard had been on the force for more than eight years, according to state police spokesman Sgt. Richard Bratz.

'My heart is with the officer's family and the officers who have served beside him,' Carney said in a statement.
