Truck Examined In Missing Carson Mother Case

By  | 

Investigators began a detailed examination Tuesday of a truck they hope will provide clues in the case of a woman missing since Nov. 10, when her 3-year-old son said she had been killed by a man now in custody in Utah.

Juan Carlos Tellez, arrested Friday in Salt Lake City, drove the 1992 GMC truck there after Bertha Anguiano, 33, disappeared. Anguiano, who possibly was having an affair with Tellez, 36, was last seen dropping another son off at school. The bloodied 3-year-old was found in a store parking lot in Dayton, about 15 miles from his home.

"The focus is on the vehicle," Carson City Sheriff Ken Furlong said. "We're doing this absolutely by the numbers - very slowly and very meticulously."

Tellez remains uncooperative, the sheriff said, adding, "He's not offering any assistance whatsoever."

On Friday, Carson City investigators were watching the truck in a parking lot in Salt Lake City when Tellez tried to leave the lot in another vehicle. Tellez was arrested after he pointed a loaded Glock pistol at officers, and is being held without bail on one count of aggravated assault.

The truck was hauled back to Carson City over the weekend, and on Monday Carson District Judge Bill Maddox signed a search warrant requested by investigators so they could conduct a forensic examination of the vehicle.

Undersheriff Steve Albertsen said investigators asked that information supporting the search warrant be sealed, and the judge granted the request.

"Due to the ongoing investigation, we don't want any evidence we've obtained released to the public at this point," Albertsen said.
