"I just want to talk to the person who shot my baby," said Shameka Harris, the victim's mother.
Harris's 10-year-old daughter, Erica, was doing nothing more than shooting hoops in the front yard. A single gunman walked up San Luis Street, aimed and fired.
"He hit my little girl three times," said Alonzo Lemmie, Erica's stepfather.
The gunman who may be as young as 16 years old. He calmly shot two other people gathered at the location on Sunday, March 2.
"It was more than our kids. There were kids. And unfortunate it was our child hit," said Lemmie.
Five days later, 18-month-old Lindsey Cervantes was shot.
"She says, 'Please help, if you know who did it or who saw anything, I don't want this to happen to another mother,'" said Lindsey's mother Maria Cervantes.
"It was just a drive-by. They never stopped. They never got out of the car," said L.A. County Sheriff's Detective Joseph Sumner.
Lindsey is in critical condition. A bullet lodged in her spine. Two other people were also wounded but were expected to recover.
Detectives say the attackers were four adult men in a gray or brown four-door sedan driving east on 137th Street. The shooter propped himself out the car armed with a semi-automatic handgun.
"We don't know if he ran out of bullets or just stopped firing," said Det. Sumner.
Detectives need the public's help to identify the gunmen in both shootings.
"So please would you turn yourself in?" pleaded Shameka Harris. "Anybody who knows who did it, please turn him in."
