A woman was arrested on suspicion of first-degree murder and other felony offenses after allegedly killing her roommate by throwing gasoline on him, then setting him on fire at their apartment in Anchorage, Alaska.

Suspect Gina Virgilio, 26, is expected to be arraigned Sunday on charges of murder, arson, criminal mischief, reckless endangerment and assault, the Anchorage Police Department said. She was arrested Saturday.

In a statement, obtained by the Anchorage Daily News, police said "investigators believe that Gina Virgilio threw gasoline onto her roommate Michael Gonzales while he was asleep on the couch in their apartment [on Friday morning]. She then lit the gasoline and then left the apartment."

Firefighters found Gonzales dead when they arrived at the apartment to fight the fire.

"The fire also completely destroyed the apartment in which the couple lives and forced the evacuation of approximately 18 other apartments. Some of the evacuated persons required medical attention at local hospitals for smoke inhalation," police added.
