Henderson died after being shot in the head at a stop sign. Her mother, Salima Wyrick, said 21 shots were fired in her daughter's direction from another vehicle, the station reported.

Henderson was driving and Wyrick was in the passenger seat.

"The bullets were coming,” Wyrick told Fox 2. “I didn't know where they were coming from, so I'm trying to grab her. I have to watch my baby die in front of me.”

Henderson’s 14-year-old brother and her 10-month-old son were sitting in the rear, according to the station.
