Homicide investigators are looking for a suspect in the early morning shooting that killed two people and seriously injured a third in Chula Vista.
Family members tell NBCSanDiego a high school student was killed outside the Vistan Apartments Friday morning.
Residents of the complex located on Oaklawn Avenue just off H Street called 911 to report the shootings around 3 a.m.
When officers arrived, they found the victim alongside a woman shot and killed in front of an apartment door.
A 21-year-old man was also injured in the shooting. He was transported to UCSD Trauma Center for a gunshot wound to his face and is expected to survive according to Chula Vista police.
Family members say the male victim and the injured man are brothers. The two were at the apartments with a 20-year-old woman described by relatives as a friend to the brothers.
The woman is Christina Selman, according to her father. She is a Chula Vista High School alum.
Investigators have not positively identified the victims. Relatives at the scene identified one as a Morse High School junior but according to the school the victim was not a registered student.
The crime scene extends into the large courtyard in the middle of the apartment complex into a parking lot on the other side and includes a Volkswagon Jetta that police say is connected to the victims.
Chula Vista police Capt. Gary Ficacci says witnesses reported seeing two young men running from the scene around the time of the shooting.
It's unclear if those two are the shooters or if they eventually became the victims in this crime.
"We're collecting everything that doesn't belong," Ficacci said.
"There are potentially numerous witnesses that we've talked to already or we haven't been able to speak to yet," he said.
"There's a lot of work to be done."
None of the three victims lived in this apartment complex, according to family members.
Selman's relatives say she would often come here to hang out with friends. Friends said she was an innocent bystander when someone began shooting at the apartment.
