The Oregon State Police reports a motorist from Antelope who had not returned home as expected has been found dead in his vehicle off Highway 293. According to an OSP statement issued Monday morning, the agency received the report that 35-year-old Nilton Vilchez Cardenas was missing on Thursday night. The car was located off Highway 293 in a marsh area concealed by tall weeds, and Cardenas was found deceased in the vehicle. Witnesses reported the driver passed them on the highway at a high rate of speed on Thursday morning around 3:00 a.m. It appears the driver left the roadway shortly after passing the witness and rolled several times before coming to rest.
