The Bexar County Medical Examiner's Office has identified the three teenagers who were found dead in a Far West Side home by San Antonio police Tuesday evening.

Alexander William Hyde, 19, who shot and killed two teenagers, died from a self-inflicted gunshot wound. According to online records, Hyde was previously arrested on suspicion of theft on March 27, 2017, but the charge was later dismissed.

The victims, both girls, were identified as Delma Pereida, 19, and Cassandra Pereida, 17.

San Antonio police said responding officers heard someone screaming for help inside a home in the 10300 block of Cone Hill Drive. When they entered the home, they found Hyde, Delma and Cassandra dead from gunshot wounds. 

Police said a 52-year-old woman was rushed to the hospital in critical condition with gunshot wounds to her arms.


Three people are dead and a woman was rushed to University Hospital in critical condition after a shooting Tuesday evening on the Far West Side, San Antonio police said.

The shooting occurred around 4 p.m. at a home in the 10300 block of Cone Hill Drive near Marbach Road.

Police spokesman Doug Greene said investigators believe the shooting is a possible murder-suicide. 

Greene said when responding officers arrived, they heard screaming coming from inside the home and later found all four victims suffering from gunshot wounds.

The three victims found dead are all teenagers -- two of them are girls, aged 17 and 19, and the third is a 19-year-old man. Greene said the man is believed to be the shooter.

One of the female victims was communicating with a friend on social media around the time of the shooting. The friend then called 911 to report the shooting, Greene said.

The woman, 52, was rushed to the hospital with gunshot wounds to her arms, Greene said.

Greene said the investigation is ongoing and homicide detectives are still processing the scene.
