A friend of University of Maryland basketball All-American Len Bias “is probably the person” who provided the cocaine that Bias used before his death, a Prince George’s County prosecutor said Wednesday night.

Arthur A. Marshall Jr., Prince George’s County state’s attorney, also said that investigators have been told that Maryland coaches were aware of drug use by some athletes; that athletes at the school may have switched urine samples to avoid being detected as drug users and that allegations of possible point-shaving have come before the grand jury hearing the case.

Investigators all along have wanted to talk to Brian Lee Tribble, a former Maryland student believed to be present in the dormitory room when Bias collapsed June 19, about the events surrounding Bias’ cocaine-induced death.

“I think it would be safe to say we’re staring at him (Tribble) very carefully,” Marshall said. “I think among the people at the moment we believe were in the room, he’s probably the person who brought the drugs in.”

Marshall said the investigation has taken new directions based on new information gathered, including allegations of point-shaving by team members during out-of-state games.

“Among some of the other rumors, (we have) specific allegations involving the fact that at least one person, Tribble, may have traveled with the team or at least been at the scene of a couple of the out-of-state games, and as a result of that there have been some statements made that maybe point-shaving was involved,” Marshall said.
