Federal authorities have charged an Arlington woman with the murder of a former Smithfield resident living in Cleveland, Ohio.

Hikers discovered the body of Matthew John Dunmire, 31, in the Terra Vista Natural Study area of the Cuyahoga Valley National Park.

According to court documents filed Dec. 8 in the U.S. District Court for the Northern District of Ohio, Dunmire died of a single gunshot wound to the back of his head. On March 5, four days before his body was found, he’d allegedly told his supervisor while out with coworkers at a bar that he was going to “meet a girl who was staying the weekend in the area.”

Using a photo from a highway license plate scanner and GPS data from the victim’s cell phone, FBI investigators determined Dunmire had traveled in a white Smart Car bearing Virginia license plate UPG-2702, a “U.S. Coast Guard” sticker and a “Virginia is for Lovers” sticker. DNA from a water bottle found near Dunmire’s body and the description provided by the victim’s supervisor as the woman who picked Dunmire up from the bar led investigators to 31-year-old Chelsea Perkins.

Investigators searched Perkins’ home on March 30, where they say they found the car, 9 mm pistol inside a woman’s purse with DNA belonging to Perkins, and two other firearms. Perkins was arrested in Pensacola, Florida, on Dec. 9.
