San Antonio police said Tuesday a 14-year-old boy was charged with capital murder in the deaths of a pregnant teenager and her mother back in April.

Officers were called out to the 100 block of Emerald Ash, just south of Loop 410 near the San Antonio Police Training Academy the night of April 9.

Police say 37-year-old Janette Quiroz was killed and 18-year-old Bernadette Jean Quiroz, was taken to the hospital. The pregnant woman died from her injuries a few hours later.

The baby was saved initially, but three days later, Tabitha Bernadett Quiroz passed away.

Police say the 14-year-old boy was already in custody for a charge of aggravated robbery. He is now charged with capital murder.
