A 73-year-old Macon man was arraigned on murder charges Wednesday, in the shooting death of a 65-year-old Jones County woman.

Frank Reeves is accused of shooting Linda Hunnicutt Tuesday, after police say Reeves motorized wheelchair made contact with Hunnicutt's car at the Murphy Express gas station on Gray Highway.

Macon Police Department Spokesperson Jami Gaudet initially said Reeves was being charged with involuntary manslaughter, but Wednesday she reversed course, saying Reeves is charged with felony murder.

It's a big change in the way the case will move through the court system, but it does little for 45-year-old Melissa Whisby of Macon, who witnessed the shooting first-hand.

When Whisby pulled into the gas station Tuesday to fill her tank, she had no idea she would soon be trying desperately to save a life.

"You know come on you can do it, you can do it, don't give up don't give up, and she took one deep breath and, and it's just like oh no, don't let her be gone," Whisby said as she recalled holding Hunnicutt and feeling the woman's fleeting pulse.

Police say Hunnicutt was shot in the chest with a .38 caliber handgun after a brief exchange of words with Reeves.

In Reeves first appearance Wednesday at Bibb County Magistrate Court, he was denied bond. Reeves told the judge he understands the charges and what happened, but the incident is more confusing for Whisby, who had stopped in front of Hunnicutt's car during the fatal encounter.

"She came around to the back, and she turned towards him, and when she turned towards him I turned down briefly, and when I looked back up again, she was like in a kneeling position falling down," Whisby said.

Whisby says nobody heard a gunshot, and witnesses thought Hunnicutt was having a seizure until they rolled her over and saw blood coming from her chest.

"I looked around and I was like who shot her, and Mr. Reeves, he said I did, he said she tried to hit me with her car," Whisby said.

During his arraignment Reeves didn't appear to show any emotion, which comes as no surprise to Whisby who says the accused shooter was strangely indifferent after the incident.

"He was too calm for one, for somebody that shot somebody, and he didn't even leave, he never tried to flee the scene, he stayed right there in his chair, his facial expression never changes," Whisby said.

Not much is known yet about Hunnicutt, but according to Facebook she is a Jones County High School graduate, and has at least one daughter who lives in Macon.

According to Reeves son, the suspected shooter recently suffered a stroke. That's the reason he was using a motorized wheelchair.
