Johanna Lissette Mejia Gayton, 17

 Johanna Lissette Mejia Gayton, a 17-year-old Latina, was pronounced dead on Saturday, Nov. 24, after her body was found off the East Fork Road about 1.25 miles east of San Gabriel Canyon Road in the Angeles Crest area of Angeles National Forest, according to Los Angeles County coroner's records. 

People looking for recyclables along the East Fork Road looked into a culvert just north of the road, along the edge of a large turnout, and spotted the teenager lying face down in the dirt around 1:15 p.m., said Los Angeles County Sheriff's Lt. Derrick Alfred.

Johanna was pronounced dead at the scene at 1:47 p.m., according to coroner's records. The cause of death was listed as blunt force trauma to the head. 

Investigators believe Johanna was struck and killed at the scene, Alfred said, but they don't have a motive for the attack. 

Johanna had been reported as a runaway several times, from her mother's home in Sylmar, and also from foster care, Alfred said. 

Anyone with information is asked to call the sheriff's Homicide Bureau at (323) 890-5500. Those wishing to remain anonymous should call  Crime Stoppers at (800) 222-8477.
