Adrien Avalos-Tavera, 23, was found dead on February 4, 2011, in a dry irrigation ditch under a bridge near Lochbuie in Weld County, Colorado. A county public works employee discovered his body, which was wrapped in a blanket and frozen after a week of below-zero temperatures. Investigators determined the death was a homicide; an autopsy found fatal blunt force trauma to the head. Authorities estimate the body had been placed in the ditch about a week to ten days before it was found.

He was positively identified by fingerprints after his family contacted investigators. Avalos-Tavera, who lived in Henderson, was last seen in late December 2010 or early January 2011, leaving a gap of several weeks before discovery. No arrests or suspects have been publicly named and the case has gone cold.

Does anyone with information about Adrien’s movements between late December 2010 and early February 2011 or who was in the Henderson area then have details to share?
