Strange Murder Case In Oklahoma: Fire Chief Murdered

This is a strange case in which a fire chief of a very small Oklahoma City suburb was shot andf killed in cold blood in his home.
From Firehouse.com: Investigators looking into the shooting death of Nichols Hills Fire Chief Keith Bryan have little to go on and are hoping for a break that will lead them to his killer, authorities said Thursday.
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.
Bryan called back from a landline on a call that lasted 1 minute and 20 seconds. She describes a man about 25 or 26 years old wearing a hooded sweatshirt who walked in through the garage door of their home.
"He shot my husband in the head. My husband is laying here bleeding on my couch right now," Bryan said on the call. "And he (the shooter) turned around to me and he said, 'Ma'am, I'm so sorry,' he said, 'But your husband should have hired me.'"
Bryan's voice rises and she sounds increasingly desperate and upset as the call goes on....
Officials have said it's possible the shooter was a disgruntled, unsuccessful job applicant.
The Nichols Hills Fire Department has not hired or interviewed anyone since 2007. The much larger Oklahoma City Fire Department hires frequently, and its chief, Keith Bryant, has a name similar to Keith Bryan's.

After listening to the news story and the 911 call and reading the story, I have to say that there is more going on than meets the eye. Seem strange that a guy would have such a grudge against a fire chief for not hiring him from 4 years ago. I don't buy the argument about confusing him with the Oklahoma City fire chief because I am sure that chief does not do the hiring.
I'm not sure what is going on there but something just isn't right with the facts in the case.
