Man convicted of killing roommate shortly after moving in

WHEATON, Ill. (AP) - A man faces up to 30 years in prison after being convicted of killing his roommate during an argument hours after moving into the man's Naperville townhome in 2014.

Twenty-four-year-old Grant Muren was found guilty Wednesday evening of second-degree murder, aggravated arson and residential arson following a bench trial in DuPage County.

Defense lawyer Paul DeLuca argued that the killing was self-defense, but called the trial and ruling "fair."

Prosecutors say Muren beat and strangled 55-year-old Charles Clark after they had a sexual encounter and Clark told Muren to leave the home.

Authorities say the Clark met Muren after the younger man answered Clark's Craigslist posting for a new roommate. Investigators said that Muren tried to burn a lease agreement and cause an explosion at the home with natural gas.
