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.
Now 32 years later police believe the beauty queen’s killing could have been part of a crime spree in which a dozen people were shot.
Police told Daily Mail that around the same time as Barraza’s killing there were several other shootings using the same type of assault rifle.
In one case, a 16-year-old boy was shot dead and nine people were wounded in National City that is about 10 minutes from San Diego.
The perpetrators used ‘the same type of assault rifle’ as in Barraza’s murder.
Police say the suspects in all of the cases were believed to be Hispanic males affiliated with a street gang from Logan Heights.
Benita Perez, Barraza’s mother, told NBC 7 San Diego: ‘Know something, see something, say something. Help us. Help us parents. Help the loved ones that need the justice for our family, for someone that you love.’
She also spoke fondly about her daughter saying: ‘Beautiful smile, beautiful personality. Everything that she did, she did with love.’
Perez took to Instagram earlier this month to mark her daughter’s birthday and shared an emotional tribute.
She posted: ‘Happy Heavenly Birthday to my Beautiful daughter Mimi. May all the Angels sing and dance to celebrate your day. Today we love and miss you so very much. Love, Mamita and family.’
San Diego police said that anyone with information about Barraza’s murder or the other cold cases should call their Cold Case Unit at 619-531-2293 or Crime Stoppers at 888-580-8477, which is offering up to $1,000 reward to anyone with tips leading to an arrest.
