Mendrick Melgoza, 16, and Carolina Ramirez, 16, were killed at about 7:10 p.m. in the 500 block of Bay View Avenue and E Street on Feb. 26.
Authorities say the young man was shot first. Ramirez tried to hide under a truck when the suspect went up to her and shot her. The teenagers were pronounced dead at the scene.
Seven months later, the victim's loved ones are pleading with people to come forward and provide tips.
"We're begging you as a family and as a community to come forward and tell authorities what you know. Any little help that can bring these murderers to justice," said one of the victim's aunts Edith Rosas.
Anyone with information on the murders is urged to call the Los Angeles Police Department's tip line at (877) LAPD-24-7.
