GRASS VALLEY—Investigators are trying to figure out how a human skull and other bone fragments turned up on a Grass Valley property.
Deputies with the Nevada County Sheriff's Department were dispatched to a property near the 1000 block of Cone Tree Trail Monday after someone reported finding bones and clothing.
Deputies were able to confirm the remains were human. The bones and clothing fragments are now at the Nevada County Sheriff's Department laboratiry for DNA testing and analysis.
Authorities say they're not sure who the bones belong to, but that it could be linked to the disappearance of a man from the area in 2004.
