Hikers found a “very old” human skull near the Hollywood sign in Griffith Park on Saturday, according to the LAPD.

The skull was spotted around 2 p.m. in the Brush Canyon area, Los Angeles Police Department Lt. Schatz said.

The location was near the Hollywood sign and about 400 feet from the Brush Canyon trail, Schatz told the Associated Press.

The discovery was determined to be the top part of a “very old” human skull, he added.

Other body parts have not been located, and the search for more bones was expected to continue on Sunday and include cadaver dogs.

Investigators did not immediately know how long the skull had been in the area, or the person’s cause of death.

LAPD homicide investigators and Los Angeles County coroner’s office officials responded to Saturday’s scene and police were expected to monitor the area throughout the night, Schatz said.

Brush Canyon is a trail located after entering the Bronson Canyon area of Griffith Park, according to a park ranger.

Saturday’s discovery comes three years after body parts were found near the Hollywood sign in the popular Bronson Canyon area.

They were determined to be that of  Hervey Coronado Medellin, a 66-year-old retired airline worker.

His boyfriend was found guilty last October of strangling Medellin.
