Andre Emmett, a college basketball star at Texas Tech who rejuvenated his professional career in the Big3 league, was shot and killed in Dallas on Monday at 37.

Emmett was in his car near his house early Monday morning when he was approached by two men with a gun, the police said. After an altercation, he was shot. The suspects fled.

Emmett, a 6-foot-5 guard, played at Texas Tech for four years, three of them under Coach Bob Knight. He finished in 2004 as the program’s career leading scorer. “Andre was one of the greatest players to ever wear a Texas Tech uniform,” Kirby Hocutt, the university’s athletic director, said Monday.

A second-round draft pick in the N.B.A., Emmett never caught on in the league, although he played 14 total games with the Grizzlies and Nets. He played professionally in the N.B.A.’s developmental league, and made numerous overseas stops.
