An 18-year-old woman who was 3 months pregnant was killed Sunday in Los Angeles when someone opened fire on a car during what police said may have been a gang-related shooting.

Maria Cordova, 18, and her boyfriend, 19-year-old Henry Sanchez, were killed when their car was struck by gunfire and crashed into a home in Boyle Heights, ABC7 reported. A third passenger in the vehicle sustained moderate injuries, officials said. One person who was inside the home was not injured.

“My brother was with his girlfriend. He was excited, you know, that he was about to be a father,” Jesse Sanchez, Henry’s brother, told ABC7.

Police said a passenger in a black SUV was the gunman. Authorities said they are investigating the shooting as being gang-related.

“I just want whoever did it to actually take responsibility,” said Jesse Sanchez, Henry’s dad. “You know, like why are you doing this to someone else?”

A gofundme account set up to help with Cordova and Sanchez’s funeral costs had raised only $160 in 18 hours.
