SANTA MARIA – Four men allegedly linked to a Lompoc area marijuana farm have been arrested for the September killing of a man whose body was left in a sleeping bag along Highway 154 near Los Olivos.

Horacio Santoyo and Dimas Santayo, both of Santa Maria, and Servando Cabrera and Jose Juan Villa-Cervantes, both of Perris, were booked Thursday for investigation of murder and were held without bail.

Santa Barbara County sheriff's Sgt. Alex Tipolt says 23-year-old Adan Cervantes Ruiz was killed Sept. 15 while the group was transporting marijuana from the grow site off Highway 1 south of Lompoc.

Investigators say Ruiz and the suspects were all involved in the pot operation. The motive for the killing hasn't been disclosed.
