(CNN) — Hikers found a human skull in rough terrain near the Hollywood sign in Los Angeles, authorities said.
Los Angeles Police said a pair of hikers discovered it Saturday afternoon at a trail in Griffith Park near the famous sign, CNN affiliate KABC reported.
The skull appeared to be a few years old, according to park rangers.
An investigation is ongoing, Lt. John Shah of Northeast Community Police told CNN.
The skull was close to where authorities discovered a decapitated head in 2012.
Gabriel Campos-Martinez was charged with murder in 2014 in relation to that case. He was found guilty last year.
