Family members of former Detroit Piston George Trapp say they are outraged because they've been told by Detroit police that the man accused of fatally stabbing Trapp will not face criminal charges.

But Wayne County prosecutors said Wednesday that the investigation into Trapp's death is ongoing and no decision about charges has been made.

Trapp, 53, died Jan. 21 at Sinai-Grace Hospital of complications from stab wounds suffered Jan. 11.

Detroit police said Trapp and his 49-year-old roommate fought at their home in northwest Detroit. The roommate was struck with an ashtray, and Trapp was stabbed in the stomach, police said.

The roommate was treated and released, but Trapp needed surgery to repair his colon. While hospitalized, Trapp developed pneumonia and lack of oxygen to the brain, and never recovered
