Jacob Jake Millison, 29, was last seen on May 15, 2015, after a night out with friends in Parlin, Colorado. Friends raised the alarm when he missed plans the next day; his mother, Deborah Rudibaugh, did not report him missing until August 2015 and told authorities he likely left because of drug problems. Friends say Jake had warned that if anything happened to him his family would be responsible.

Investigators searched the family’s 700-acre 7-11 Ranch in July 2017 and found human remains near a corral that were later identified as Jacob Millison. Deborah Rudibaugh reportedly confessed, saying she shot him in the head in the early morning of May 16, 2015, and claimed self-defense amid ongoing disputes over the ranch’s future. Authorities questioned whether a frail woman could have moved Jacob’s 170-pound body alone and examined her daughter Stephaine Jackson and son-in-law David Jackson.

Cell phone records placed Stephaine and David at the ranch around the time of the killing, and investigators uncovered deleted messages and social posts that they say are linked to the night in question. The case centers on a family feud over control of the valuable ranch. Does anyone have information about Jacob’s last known movements or the family’s activities on May 15–16, 2015?
