CORTEZ, Colo. (AP) -- Authorities say human remains found near Bayfield in southwest Colorado are those of a Pagosa Springs man who was reported missing last month.

The Cortez Journal reports that cattlemen found the remains of 59-year-old David Bruce Ritchie on Tuesday in a rugged area north of U.S. Highway 160 near the Archuleta-La Plata county line.

Family friend Liz Anderson says Ritchie wandered off the morning of Aug. 5 and had been taking a new medication to treat depression and insomnia. She says the medication may have contributed to feelings of paranoia and caused Ritchie to take flight, adding that it appears the man died of exposure.
