Police spent Tuesday and Wednesday interviewing potential witnesses, working to gather descriptions and canvassing areas to confirm reported sightings.

\"These men are exhausted,\" Police Chief Joe Prentice said in a Facebook post shared on Wednesday. \"I am sending them home to get rested and we will start fresh tomorrow, unless something time sensitive comes in overnight.\"

According to investigators, two of the men are believed to have cellphones with them, however, attempts to contact them go straight to voicemail.

Chastain's cellphone was tracked to an area south of Okmulgee, but was turned off or lost power at some point. Officers checked the area, but found no sign of the men, police said.

Anyone with information regarding their whereabouts is urged to contact the Okmulgee Police Department.
