Lewis Newton, 42, was found dead under a tarp near his home in Palermo, California, on October 11, 2013. Authorities determined he died of a gunshot wound and the Butte County Sheriff’s Office classified the case a homicide.

Investigators linked Newton’s death to a marijuana grow operation at the property. Officers reported finding 40 marijuana plants that were part of a Prop 215 grow, but officials have not disclosed how the garden factored into the killing. The murder weapon has not been recovered and many scene details remain undisclosed as detectives work to piece together Newton’s final hours.

Newton’s family described him as a Gentle Giant who helped others and a fund was set up for his surviving son. If anyone has information about the Palermo grow site, the events of October 11, 2013, or leads that could help identify those responsible, please share what is known.
