Tucson police are searching for a suspect in a drive-by shooting early Saturday morning that left one man dead and another seriously injured. At about 2 a.m. three soldiers stationed at Fort Huachuca in Sierra Vista were leaving Tucson hip-hop club Envy, 6211 E. Speedway, following an argument with the suspect, Jurel Dionne Roberson, 21. As the three soldiers were driving west bound on Speedway, Roberson pursued them in a borrowed car, pulled up along side the victims and fired several shots into their car.
