Laquann Sloan was 16 and from Oakland when she was shot and killed on June 8, 1989, while making a turn through an exit on Interstate 580. Her death was one of a series of attacks attributed to Charles Arnett Stevens, later called the I-580 Killer, who used a semiautomatic handgun and targeted motorists along the interstate.

Stevens began the spree on April 3, 1989, and was arrested on July 27, 1989. Investigators linked him to multiple scenes with shell casings and palm prints and relied on witness testimony from survivors. Laquann was one of four people murdered during the spree; other known victims were Leslie Ann Noyer, Lori Anne Rochon, and Raymond August.

The case underscores the random, lying-in-wait nature of the attacks and the forensic and eyewitness evidence used to build the prosecution. If anyone knew Laquann or has information about that night, please come forward.
