A man in Volusia County, Fla., woke up Thursday and found his head bleeding, drove to work and left a note for his boss before going to the hospital and finding out he had a bullet lodged in his brain.

When Glen Thomas Betterley, 53, noticed the blood Thursday morning he asked his girlfriend if she had struck him. Emma Lorene Larsen, 65, said no.

So, Betterley got ready and went to work.

During the day, Betterley wrote his employer that he could not stay at work and was going to the hospital for treatment.

When he arrived, doctors determined he had been shot in the forehead.

Officers called his girlfriend at her Orange Avenue home and during the phone conversation they head a single gunshot from inside the house.

Officers forced entry into the home and found Larsen with a gunshot wound to the head.

She died of her injuries.

"Certainly unusual, certainly surprising for our little neighborhood here," a neighbor told Local 6 News. "Yeah, I'm pretty shocked."

Betterley was in stable condition Friday.

Detectives are trying to determine what led up to the shooting.
