SAN BERNARDINO, Calif. -- Timmy Hilliard is a social worker at the Inland Regional Center.
He was in his office on the third floor when the shooting started. As police moved in Hilliard took out his phone and started recording.
"I got a text from a colleague saying there was an active shooter," he recalled. "I got up out of my desk opened my door went into the hallway and I saw my colleagues running around screaming, crying."
Hilliard had a birds eye view of the entrance and the exit that the shooters went in.
"At first what I saw was the swat team coming into the back door about five or six looking for active shooter," he said. "As well as in the back there was a gentleman deceased on the bench I assumed as well as a female about 10-or-15 feet away laying in a pool of blood deceased as well."
Hilliard said he thinks they were trying to flee, and then were shot.
"The female, I assume, do to her positioning and the way she was facing with her back to the building she was fleeing," Hilliard said.
Some of the most disturbing things about Hilliard's video is to see the bodies being brought out.
"They were grabbing as much as they could arms, feet," Hilliard explained. "They had them in chairs just trying to get them out of harms way...seeing if they were critical and or deceased."
Hilliard said he began to realize how grave the situation was when the sixth body came out.
"Just seeing the effect of it all. At first I saw the two bodies and okay its two bodies, not saying that its not bad, but its two bodies it may not be that bad," he said. "And by the 12th body I stopped counting."
Hilliard said he saw at least 12 bodies.
The shooting in San Bernardino is the worst mass shooting in America since the Sandy Hook shooting.
"Its intense, you don't realize what it is until you get out of the situation," Hilliard said.
Hilliard said he takes many lessons from this situation.
"Don't take anything for granted I mean I have a two and half year old daughter, sorry," he said through tears. "So I thought about her."
Hilliard and other survivors were taken to a church after they were removed from the building where they were able to reunite with colleagues and loved ones. Hilliard said he can't wait to spend more time with his daughter.
