An investigation is underway after a man was shot and killed early Wednesday morning in Orange County, deputies said.

A woman called 911 around 3 a.m. stating she was inside her home sleeping when she heard a single gunshot. The shooting happened along Ohio Avenue in west Orlando, just north of State Road 408.

She went outside and found a man, later identified as 24-year-old Anthony S. Wheeler, in her front yard.

Wheeler was transported to Orlando Regional Medical Center, where he later died.

Lt. Paul Hopkins, of the Orange County Sheriff's Office, urges residents in the area to be aware of their surroundings.

"You don't have to live paranoid, but always be aware," he said.

No suspect information has been released.
