The S.C. Highway Patrol has finished its investigations into three hit-and-run accidents in Berkeley County and will announce the results during a 2 p.m. press conference today, including for a case in which a Cane Bay High School student was killed.

Charges may be announced in some of the cases.

The incidents include:

• A January accident in which a passing motorist found the body of Angelo Mendes, 32, of Moncks Corner, on U.S. Highway 17A near Murrells Inlet Lane.

A woman later contacted the Highway Patrol after friends and family members told her that the suspect vehicle described in news reports matched the description and damage found on her Ford F-150 pickup truck. She originally told investigators she was unaware she'd hit anybody.

• A March 6 hit-and-run collision that killed a Cane Bay High School student. Ronny Gallardo, 17, was struck by a car while riding his bike along U.S. Highway 176 near Alexander Circle. He died later at the Medical University Hospital.

Troopers say a woman was driving a vehicle that hit Gallardo. She left the scene, but returned about an hour later, it was reported at the time.

Gallardo was an honor-roll student. He was staying with an aunt and uncle who lived just a couple of hundred feet from where he was struck.

• An April 16 incident in which Goose Creek man lying in a road was hit by a car and killed. Erhesto Mungaray, 40, was lying on Old Back River Road when he was hit by a car about 10:24 p.m. Mungaray died of his injuries at Medical University Hospital.

The press conference will be held at the patrol's North Charleston office, 8741 North Park Blvd.
