An itinerant man who committed a string of violent crimes across Colorado and Utah in 2017 pleaded guilty Friday to killing a Golden man.

Austin Jeffrey Boutain, 25, faces life in prison without parole after he pleaded guilty Friday to killing Mitchell Ingle while robbing his trailer. He will be sentenced Oct. 3. His wife, Kathleen Boutain, 25, faces 20 charges in connection with Ingle’s death and is awaiting extradition to Colorado.
The Boutains in 2017 were homeless and subsisted by stealing marijuana from dispensaries to resell, which led to their encounter with Ingle, 63, Boutain said in his confession. The couple was drinking and smoking marijuana with Ingle in his trailer, but Boutain became angry when Ingle suggested the three could have sex.
After Ingle went to sleep, Boutain attempted to kill him to steal his trailer. He initially shot Ingle with a crossbow but only wounded Ingle’s wrist. Then he slit his throat. Boutain decided not to take the trailer but stole three guns, a pickup and other items before traveling to Utah with his wife.
Boutain used one of the guns he stole from Ingle to kill Guo. Golden police found Ingle dead during a welfare check after Boutain was arrested in Utah with his clothes and gun.
