ORANGE COUNTY, Fla. -- Gunfire erupted in a parking lot of a busy Home Depot store, leaving one person dead and two gunmen on the loose.

Eyewitnesses at the Home Depot on West Colonial Drive and Hiawassee Road say they heard several shots around 6 p.m. on Wednesday night. "I was sitting in my car in the parking lot and heard seven gunshots," said Courtney Kanisters, an eyewitness.

Investigators say two suspects opened fire on a man inside a white van. The driver of that van was rushed to Orlando Regional Medical Center, but died in the ambulance.

A few blocks away, deputies found a truck parked in a Gotha neighborhood, which they believe was used by the gunmen. Deputies blocked off the neighborhood as they searched for two gunmen.

Detectives believe the shooting may have started out as a drug deal. At this point, they're trying to figure out if the two suspects fired all the shots, or if the victm also fired a gun in the busy store parking lot.

"Sadly we had one death, but there could've been more," said Jim Solomons from the Orange County Sheriff's Office.

The victim's name has not been released.
