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.
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.
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.
