Lawrence OConnor, 56, was found dead on September 5, 2016, at a rural property on US Forest Service Road 3N14 South Fork Mountain near Hyampom, California. He and 47-year-old David Sims were discovered together; autopsies showed both died from gunshot wounds in what authorities have classified as a double homicide.

The property where the bodies were found was associated with a marijuana grow operation, and investigators have considered motives connected to cultivation and distribution disputes. No arrests have been made and the case remains unsolved; the Humboldt County Sheriff’s Office is asking anyone with information to come forward.

Are there tips, memories, or local knowledge about the property, people who frequented it, or activity in the area that could help investigators?
