Authorities release 911 calls in Nichols Hills fire chief's death

Jessica Brown, spokeswoman for the Oklahoma State Bureau of Investigation, said investigators are talking to as many people as they can, hoping someone will have the key piece of information that could lead them in the right direction.

“We're doing forensic testing on items,” Brown said. “One of the things our agents did today was go back and canvass the neighborhood again, ask people if they saw or heard anything.”

The state medical examiner ruled Thursday that Bryan died from a single gunshot to the head. Mustang police on Thursday released recordings of two 911 calls Keith Bryan's wife, Becky, made Tuesday night after he was shot at their home in the 1300 block of W Rose Hill Drive.

In the final seconds of her second call to 911, Becky Bryan describes her husband as “gasping for air.”

“He's dripping, he's like moving,” Becky Bryan said on the call, placed about 10:05 p.m. “I've got to have somebody here.”

Her voice is heard during the first 17 seconds of the first call, placed from her cellphone, until the call apparently goes dead. Bryan first asks if she's reached Mustang police, then begins to describe “a young man about 25” until her voice drops off the call.
