LANCASTER, Calif. (KABC) -- Authorities are searching for an 18-year-old accused of fatally shooting his teen sister in Lancaster.
The shooting was reported Tuesday around 5:30 p.m. in the 1700 block of West Avenue J15.
The victim was described as a juvenile female in her teens. She was brought to a local hospital and pronounced dead there.
"She was only 13 years old, had her whole life ahead of her," said Vanessa Zamora, the victim's aunt, who described her as "the brightest girl I've ever met - happy, very outgoing, smart, loved school, loved to be with her friends."
The girl's brother, identified as 18-year-old Eddie Alvirez, has been identified as the suspect after he was earlier described as a "person of interest" in the case. He fled on foot from the scene shortly after the shooting, authorities said.
In an interview with local TV reporters, Zamora appealed to her nephew to "just do the right thing" and turn himself in.
"I mean, the damage is done. There's nothing you can do now, she's gone, you can't bring her back," the aunt said. "Just take the consequences as you should, as an adult."
Alvirez is described as Hispanic, 5 feet 4 inches tall, weighing 110 pounds, with black hair and brown eyes. He was last seen wearing a white T-shirt, gray or black shorts, and Jordan shoes.
Authorities say he frequents the Lancaster area.
Anyone with information is asked to call Los Angeles County Sheriff's Department's Homicide Bureau at (323) 890-5500. Anonymous information can be provided to Crime Stoppers at (800) 222-TIPS (8477).
