HELENA, Mont. (AP) — A man convicted of deliberate homicide in the slayings of a couple in their Montana home has been sentenced to 80 years in prison.

The Independent Record reports Kyle Hamm was sentenced Monday for the deaths of 64-year-old Charla Taylor and 61-year-old David Taylor, who were found dead in their home north of Helena in March 2018.

The couple’s son, Kaleb Taylor, pleaded guilty to deliberate homicide and was sentenced to life in prison. A third defendant, Journey Wienke, also was convicted and is awaiting sentencing.

Prosecutors say the Taylors had confronted their son after he burglarized their business to get money to pay a drug debt. Hamm told investigators the three drove to the home together the night of the slayings but said he stayed in the truck with the door open as Kaleb Taylor and Wienke went inside.

Hamm was charged under a state law that says a person who is “legally accountable” for a robbery, assault with a weapon or other forcible felony that causes the death of another person is guilty of deliberate homicide.

Hamm will be eligible for parole in 20 years.
