"I just saw a guy in the building that has a hat on, a straw hat," an officer can be heard saying four minutes and 22 seconds into the audio. (Taylor had died blonde hair on top.)
"Whoa, we got shots fired!" an officer says just seconds later.
"Make sure they're called, make sure they're called!" a panicked voice, presumably of the shooter, can be heard saying.
The officer made no indication of a struggle.
The Arlington Police Department told The Huffington Post they have not released the audio file and "cannot speak to the validity of this video or source." They added that "It’s possible that someone obtained portions of the audio from a police scanner website."
A medical examiner ruled Taylor's death a homicide, citing "gunshot wounds to the neck, chest and abdomen," ABC reported.
At a press conference Saturday night, Arlington Police Chief Will Johnson said audio and video of the incident wouldn't be released until all statements have been made, which could take between 7 to 10 days.
Surveillance video given to NBCDFW by the dealership shows Taylor jumping on a car and trying to pry off the windshield. What his intentions were will never be known, since he was killed a short time later.
Officer Miller graduated from the police academy in March, and was still in the midst of finishing a 16-week field-training program, the Fort Worth Star-Telegram reported. Miller was with his training officer at the time of the shooting.
On a Twitter account that appears to belong to Taylor, messages talk about being afraid of dying young, and feeling a lack of safety around cops.
