Los Angeles police said Saturday hikers found what appears to be a human skull in Griffith Park.

Lt. Ryan Schatz said the two hikers stumbled upon the skull around 2 p.m. about 400 feet from the Brush Canyon trail near the Hollywood sign. He said the skull appeared to be several years old.

Other body parts have not been located. The search for more bones and body parts is expected to continue Sunday and include cadaver dogs, according to KTLA.

Schatz said coroner and homicide investigators closed access to the area. Investigators are still determining how long the skull had been at the park or the person’s cause of death.

Covering 6 ½ square miles in the eastern Santa Monica Mountain range, Griffith Park is considered the largest municipal park in the nation.

KTLA reported that the discovery of the skull comes three years after body parts belonging to Hervey Coronado Medellin were found in the Bronson Canyon area.

Medellin was a retired airline worker and last October his boyfriend was found guilty of strangling him to death.
