TAMPA, Fla. (WFLA) — Tampa police said an arrest was made Thursday in the murder of a 14-year-old girl in May.

The Tampa Police Department said 44-year-old Ronny Walker was arrested on a premeditated first-degree murder with a firearm.

Police had been investigating the death of 14-year-old Nilexia Alexander since she was found dead with an apparent gunshot wound on Floribraska Avenue on May 6.

TPD said they were able connect Walker’s vehicle as the vehicle in the area around the time of the murder. They also found evidence on his cellphone that placed Nilexia in his car around the time of the murder.

A search of Walker’s vehicle also found Nilexia’s DNA in the car.

Walker was arrested by U.S. Marshals Thursday afternoon. The investigation is ongoing.

Veronica Denson says she can never forget Walker’s name and face. He was convicted of murdering her mom Elaine Caldwell in 2003.

“My mom was a good person,” Denson says.

Denson thinks about her mom everyday.

“I remember her cooking and having parties, my mom loved to party,” Denson said.

Denson says Walker spent several years in prison and got out. She got a call two months ago, he was getting out of prison again.

“If he would’ve been in prison, he would have never had a chance to kill this baby, he killed a baby, 14-years-old,” Denson said.

She hopes this time, Walker stays locked up, so no other family has to experience this pain.

“If they let him out again what is he going to do next time,” Denson asked.

More details are expected to be released by police at a press conference Friday morning. You can watch it live on WFLA, WFLA.com and the WFLA app.
