LANCASTER -- The Lancaster County Sheriff's Office is investigating what led to a Saturday night shooting that left one man dead and another injured.
Around 9:15 p.m., deputies were called to 1552 Memorial Park Road, about a mile outside the Lancaster city limits, for a hit-and-run involving a pedestrian, Sheriff's Office spokesman Tom Holland said.
They found Marcus Robinson, 24, of Lancaster lying in a ditch with what authorities said was a broken leg. It's not clear how he got there.
Robinson's 16-year-old brother, Alphonzo Marquee Robinson, was at his side.
Alphonzo Robinson walked away, then returned as his brother was loaded in an ambulance, Holland said.
After talking with his brother, Alphonzo Robinson walked away again, Holland said,
Several minutes later, deputies heard shots.
Paul Levar Brown, 28, who stood in the crowd looking on, was shot in the back. Another onlooker, Terrance Grier, 51, was shot in the arm, Holland said.
Brown was taken to Springs Memorial Hospital, where he was pronounced dead, said Lancaster County Coroner Mike Morris.
Grier was taken to Carolinas Medical Center in Charlotte for treatment and was released.
Alphonzo Robinson is charged with murder and will be tried as an adult, Holland said.
Investigators aren't sure whether there actually was a hit-and-run, Holland said, but Alphonzo Robinson told deputies someone intentionally swerved to hit his brother.
Some witnesses at the scene said there wasn't a crash, Holland said.
