Just two days before she was killed, former Miss Teen San Diego winner Mimi Barraza had been celebrating her 21st birthday.
Barraza was talking with a group of friends outside one of their homes in the early morning of September 4, 1993, when a white Chevy Astro-Van pulled up and an occupant began shooting, San Diego police said.
Barraza, who was mother to a two-year-old daughter, was struck in the head and killed.
Police said the van sped away from 1600 South 39th Street and was found 'several hours later that morning' on the intersection of 19th and G Street in San Diego.
The vehicle had been reported stolen one day earlier. Police found casings from 'several different caliber weapons' in the van, as well as at the crime scene.
