A 45-year-old woman was struck and killed by a car in Mulberry early Sunday.

According to the Polk County Sheriff's Office, Julie Ann Melvin of Mulberry was standing in the travel lane of State Road 60 just west of 5th Avenue NW around 3 a.m.

At the same time, Renee Lynn Costanza, 24, of Tampa was traveling west on S.R. 60. Costanza applied her brakes when she saw Melvin, but her wheels locked up and the car slid into Melvin.

Deputies said Costanza made a U-turn on S.R. 60 and began to search for the victim. Emergency responders arrived first after being dispatched when a witness reported the crash.

EMTs attempted life-saving measures on Melvin, but she died at the scene.

Speed nor alcohol was not believed to be a factor in the crash. But traffic homicide deputies are continuing to investigate.
