The incident happened at about 9:30 p.m. in front of the girl's home on the 600 block of West 49th Place. According to police and witnesses, the victim, Kimberly Arrue, was playing with a ball in her front yard when the ball went into the street.
"She went to go get the ball across the street and a car just popped out of nowhere and just hit her," said witness Jonathan Antepara. "He never stopped and just kept on going."
The victim's sister Diana Arrue said she was telling her sister not to cross when the car struck her.
"A very beautiful little girl that was very intelligent, and just out of nowhere, in the blink of an eye, dead," Arrue said.
The young girl's father picked up her body from the street and laid her on the front lawn. The second grader was rushed to a nearby hospital, where she was pronounced dead.
The only description police have of the SUV is that it is black. LAPD Sgt. Samuel Mark said according to debris at the scene, the vehicle has a broken headlight. Authorities said the car may also have front-end damage.
Anyone with information was asked to call Los Angeles police at (877) LAPD-24-7.
