The ex-boyfriend of a 16-year-old girl is wanted for questioning in her stabbing death early Friday morning in Pico Rivera, according to the Los Angeles County Sheriff's Department.
Investigators responded at 3:15 a.m. to the 9800 block of Shade Lane in Pico Rivera, a community about 13 miles southeast of downtown Los Angeles, authorities said.
The victim's mother told investigators that she woke up to the sound of screams from her daughter, who ran upstairs after she was attacked. The girl was pronounced dead at the scene.
The intruder entered the home through a backdoor while the girl, Elena Lillian Moore, was in her downstairs bedroom, deputies said. After the stabbing, she ran upstairs to her mother's bedroom.

No arrests were reported Friday morning.
"Based on the victim's statements to her mother prior to her collapse, the victim's ex-boyfriend is being sought to determine if he was involved in the attack," sheriff's officials said in a news release.
The teens met at Ruben Salazar High School and had been dating for about a year, the mother told investigators.
"A lot of people are going to miss her," said Justin Flores-Garcia, a friend of the victim. "She was always there for everyone. No clue why someone would do that to her."
