Headline Goes Here

JACKSONVILLE, Fla. - A woman who police said shot and killed her ex-boyfriend outside a Westside post office in March was sentenced to life in prison without parole Wednesday.

According to court records, 23-year-old Arianne Myles pleaded guilty to murder in the second-degree this week.

Investigators said in March 2013, Myles happened to see her ex-boyfriend, 23-year-old Harold Davis Jr., while she was driving by. Police said she parked her car behind his, got a gun from the back seat and started firing.

Several witnesses, including the person in the car with Myles, saw her shoot Davis several times, killing him, then get back in her car and head north on Blanding Boulevard, investigators said.

Retired JSO Officer Mark Shinholser was across the street and heard the shots. He saw Myles get in the car and started following her, police said. He called 911, alerting police to where she was, and officers started following her.

A person in the car with Myles told investigators they didn't know Myles was going to shoot Davis, police said. That person stayed behind after Myles left, police said.

"Apparently they were traveling and I guess as bad luck would have it, she looked over and saw his vehicle at the post office, turned in there," JSO Lt. Rob Schoonover said in March 2013. "Like I said, the witness said, 'I had no idea she even had a gun in the car.'"

Officers pursued Myles until she caused a crash at the intersection of Timuquana Road and Seaboard Avenue, about a mile from the shooting scene, police said. They said she struck a car carrying a woman with children, before she was taken into custody.
