Elene Lillian Moore died at the scene of the 3:15 a.m. stabbing in the 9800 block of Shade Lane, according to Ed Winter, assistant chief of operations at the Los Angeles County Department of Medical Examiner-Coroner.
“Detectives learned that the victim’s mother was suddenly awoken by her daughter’s screams that she had been stabbed as she staggered into her bedroom and collapsed,” Deputy Guillermina Saldana of the Los Angeles County sheriff’s Information Bureau said in a written statement.
“(The mother) believed she had been stabbed by her ex-boyfriend,” Lt. Eddie Hernandez of the sheriff’s Homicide Bureau said.

The attacker had fled the home before deputies arrived and remained at-large Friday afternoon.
“Based on the victim’s statements to her mother prior to her collapse, the victim’s ex-boyfriend is being sought to determine f he was involved in the attack,” Saldana said.
Detectives identified the “person of interest” as 17-year-old Rory Murga.
Moore and Murga had dated for about a year, Hernandez said. “They broke up recently, about two weeks ago.”
The circumstances of the fatal stabbing remained unclear, officials said. The stabbing took place on the first floor of the home, while the mother’s room was upstairs.
“At this point, we’re not sure if he forced his way in or was let in by the victim,” Hernandez said. “We’re not sure if there was an argument that precipitated that stabbing.”
Moore had been stabbed multiple times, Winter said.
Both Moore and Murga attended Ruben Salazar High School in Pico Rivera, neighbor Jaime Lugo said.
“She was a really nice girl,” he said. “She was always really friendly. She was always really open with people.”
“Just shocking. I think that’s like really the only word that can describe it,” Lugo said.
Anyone with information is urged to contact the sheriff’s Homicide Bureau at 323-890-5500. Tips may also be submitted anonymously to L.A. Regional Crime Stoppers at 800-222-8477.
