Autopsies reveals how San Bernardino victims were massacred in a room decorated for the holidays and their bodies were left clustered around festive tree

Three of the 14 people killed during the San Bernardino shooting were found clustered around a Christmas tree in a conference room that had been decked out for the holidays.

Autopsies released by the county described the chaotic scene found by investigators after the carnage in December last year.

Public health workers had gathered for an annual training session when their coworker Syed Farook and his wife, Tashfeen Malik, opened fire, dressed in black and wearing ski masks.

Nine people died inside the 85-by-40-foot conference room that day. Three were found just outside the building and two were pronounced dead at a nearby triage station.

'The room was in disarray,' the autopsy reports state. 'The chairs, food, property and decorations were strewn about the room. 

'There were several dozen cartridge casings around the room. There were multiple bullet holes in the ceiling, walls, furniture and floor.'

San Bernardino County released the heavily redacted autopsies as part of a public records request by The Associated Press.

Some of the ceiling tiles in the conference room had come crashing down. 

The body of 46-year-old Harry Bowman, the father of two daughters, was found closest to the northernmost door of the conference room.

Bowman, who had begun working for the county not long before the attack, was shot five times. 

Eight other bodies were found in the conference room, some more than 50 feet from where Bowman lay.

Three victims, all men, were left clustered near a Christmas tree. 

Three other victims died just outside the building.

Two more, 45-year-old Shannon Johnson and 46-year-old Bennetta Bet-Badal, were deemed the most likely to survive but were later pronounced dead at a triage station nearby.

It is unclear how long they lived before then.

Johnson's autopsy shows he died of a gunshot wound to the right thigh, though he also was hit in the back, elbow and buttocks.

One of his co-workers has credited Johnson with saving her life, saying he held her close when the bullets began flying and told her: 'I got you.'

Bet-Badal, a native of Iran who came to the US when she was 18 to escape Christian persecution, died of a gunshot wound to the abdomen, according to her autopsy. She had also been hit in the legs and chest.

Her three children were 10, 12 and 15 at the time of the attack according to a Go Fund Me set up for the family. 

Twenty-two people survived the shooting. 

The San Bernardino attack was the deadliest terror strike on US soil since 9/11.

The FBI said Farook and his wife, Tashfeen Malik, were radicalized before they met online and communicated privately about jihad and martyrdom before they married.

Both died on the day of the attack in a shootout with police. 

Their autopsies were not released Friday. County spokesman David Wert said the investigations into their deaths had not been finished and had no estimate of when they would be ready.
