WELD COUNTY, Colorado - Colorado authorities say two men who died in a pickup crash in rural Weld County on October 17 were from Oklahoma.

Weld County is located northeast of Fort Collins.  

In a news release Monday, the sheriff's office said the men have been identified as Zachary Allen Moore, of Prague and Joshua Trae Foster, of Muskogee.

Sheriff Steve Reams said the case is being investigated as a suspicious death.

"Circumstances discovered during the investigation indicate that this was not a traffic accident," he said.

Firefighters were called after a Colorado state trooper spotted a fire in the Pawnee National Grassland and found a 2007 Dodge Ram pickup burning.  
Deputies said the truck was so badly burned that they couldn’t identify the two people inside.

Anyone with information regarding the deaths of Moore and Foster is asked to call the Weld County Sheriff's Office at 970-356-4015 or Northern Colorado Crime Stoppers at 1-800-222-TIPS.
