Police in southern Utah are looking for two men who seem to have vanished without explanation.
Washington County Sheriff's deputies said Chad Grijalva and Derek Davis, both 34, disappeared on Oct. 24, telling friends and family they were travelling to Cedar City and planned to return to St. George that evening.
The men never returned, deputies said.
"They've dropped completely off the face of the earth," Washington County Sheriff's Lt. Jake Adams said Thursday. "There's been no financial transactions. They've just disappeared."
Sheriff's deputies said they have evidence that suggests Grijalva's cell phone was used in the Delta area on Oct. 24 at about 7:30 p.m. It was again used on Oct. 26 in the Salt Lake City area at 11:09 p.m.
"This is the last known usage for the cell phone that we have been able to identify," Adams said.
Family members are growing concerned. Sheriff's deputies have listed the two men and Davis' truck as missing on a national crime database. Police in Millard County and along the Wasatch Front have also been contacted.
On Thursday, Washington County Sheriff's deputies released photos of the two men in hopes of generating tips to find them. Adams said the men are not wanted for anything, but family members are anxious for any news.They were last seen in a white, 1990 Ford Ranger pick-up with Utah license plate 429UKL. Anyone with information on their whereabouts is urged to call the Washington County Sheriff's Office at 435-656-6500.
