Joshua Lamar Carter's family had been looking for him for two or three days, a neighbor said.

Then, shortly before the sun came up yesterday, police were called to a parking lot in Seat Pleasant, where a body lay on the ground. Joshua, who was 14, had been found. He had been shot repeatedly in the upper body, said Cpl. Joe Merkel, a Prince George's County police spokesman.

Late yesterday afternoon, the neighbor said, police delivered the news at a house on Vale Place in the Capitol Heights area, where the teenager had lived with his mother, brothers and sisters.

Investigators have not determined a motive or identified a suspect in the slaying, Merkel said late last night.

A sister, identified as Keya Johnson, told WRC-TV (Channel 4) last night that the youth "was at the wrong place at the wrong time.

"He was on his way home, and he got caught up," the sister said.

The place where Joshua's body was found about 6:45 a.m., in the 6900 block of Central Avenue, is about a half-mile east of the Addison Road Metro stop and about a mile from the street where the youth lived.

A neighborhood resident, who spoke on condition of anonymity, said Joshua was a member of the extended family of prominent Washington area boxer Derrell Coley. The youth lived in a house that is listed in public records as a former residence of the boxer.

Coley, who fought Oscar De La Hoya in New York's Madison Square Garden in a welterweight title elimination bout in 2000, could not be reached for comment last night.

More than 100 people have been slain in Prince George's County this year. Many of the killings have occurred in circumstances similar to yesterday's -- inside the Beltway, late at night or early in the morning, often near commercial strips.
