Police initially said the errant bullet came from someone in a passing black SUV, but the L.A. County Sheriff’s Dept. now says Villa was shot by someone nearby who was on foot at the time.

At an LASD press conference Thursday, Karla’s mother Guadalupe Villa said through an interpreter that she had to hide her pain from her other children.

“I don’t cry in front of them,” said Villa. “I have to be strong and not let them see me suffering.”

“She explained how tragic this event has been for her family and how much hurt and pain it has brought to them,” Det. Al Torres told CBS2 News. “Karla has three younger sisters that have suffered along with her.”
