De La Salle High School student Darius Jones collapsed while playing a basketball game. He was pronounced dead at a hospital a short time later.
A 15-year-old Pittsburg student died Sunday during a De La Salle basketball game.
Darius Jones collapsed during a game at Diablo Valley College. People at the scene gave him CPR prior to an ambulance taking him to John Muir Medical Center, where he was pronounced dead.
The sheriff's office will not be making any determination as to his cause of death until they receive results from toxicology tests, which can take four to six weeks, Contra Costa County sheriff's Capt. Daniel Terry said.
A spokesperson for the school, a private, Catholic high school in Concord, was not immediately available for comment.
A Facebook page set up in Jones' memory is asking De La Salle students to wear black on Tuesday. The school was closed Monday for the Columbus Day holiday. The page has hundreds of fans.
