DELRAY BEACH, Fla. — The family of University of Alabama Birmingham running back Gregory Bryant searched for answers Monday, saying they don’t know why anyone would fatally shoot him as he drove on Interstate 95.

Allen Mosley, Bryant’s uncle, said Bryant always had a smile and was never angry. He said Bryant died Sunday morning, but remained hooked to machines Monday while the family decides whether to donate his organs.

Bryant was shot early Saturday as he and a friend, Maurice Grover, were driving back to the home of Bryant’s grandmother. Bryant, 21, was in town just a few days to spend Mother’s Day with his mom and grandmother, Mosley said.

“I guess God needed a running back and Greg’s number was called,” Mosley said. “He was a hungry, humble kid who just had a passion to play pro football.”

A police spokeswoman, Detective Lori Colombino, gave no updates Monday on the investigation.
