A car involved in a multi-vehicle wreck in College Park late Sunday that killed three people and critically injured a fourth was reported stolen that morning, Prince George's County police said yesterday.

Police said the driver of the car, a 1991 Hyundai Excel, lost control as he was rounding a curve while going south on Paint Branch Parkway, just east of Route 1. The Hyundai sideswiped a 1998 Ford traveling in the same direction and struck a concrete barrier, police said. The Hyundai then spun into oncoming lanes of traffic, flipped over and landed on the hood and roof of a 1988 Saab 9000, police said.

The driver of the Hyundai, identified as John Adrien Roger Jr., 20, of the 5300 block of Emerson Street in Hyattsville, was pronounced dead at the scene, police said.

Two 15-year-old passengers in the Hyundai were also killed: Michael James Mcartney, of the 5300 block of Riverdale Road in Riverdale, died at the scene. His friend and neighbor, Adam Hannah, also of the 5300 block of Riverdale Road, died of his injuries early yesterday at Prince George's Hospital Center in Cheverly, police said.

The driver of the Saab had to be pried out of his vehicle and was taken to Prince George's Hospital Center, where he was listed in critical condition yesterday, police said. Friends identified him as Eric Bishop, 21, of Worton, Md., a student at the University of Maryland at College Park. The driver of the Ford was not injured, police said.

Investigators said excessive speed may have caused the accident.

Police said the Hyundai was reported stolen about 10 a.m. Sunday from the residence of its owner in the 7700 block of Topton Street in New Carrollton. They declined to say whether the young men riding in the car were suspected of stealing it.

Hannah and Mcartney were students at Bladensburg High School, neighbors said. Roger had lived with his family for many years in the unincorporated community of Rogers Heights, east of Kenilworth Avenue between Bladensburg and Edmonston, a neighbor said.

Bishop is the chief engineer for WMUC, the campus radio station at the University of Maryland, where he is considered a technological whiz, said Tom Maronick, a news producer for the station.

"People are just in shock right now about what happened," Maronick said. "He's a brilliant kid and he knows electronics better than anyone at WMUC. This kid has a lot of talent."

Staff writer Eugene L. Meyer and researchers Bobbye Pratt and Margot Williams contributed to this report.
