Matthew John Dunmire was a 31-year-old aspiring musician and father of two from Cleveland, Ohio, described by friends and family as a free spirit who loved playing his guitar. He was last seen on March 5, 2021, leaving the Tiki Underground restaurant with a brown-haired woman in a white Smart car after telling coworkers he planned to meet a woman from out of town for the weekend. Hikers found his body on March 7, 2021, in a wooded area of Cuyahoga Valley National Park near Terra Vista Cemetery. An autopsy determined he died from a single gunshot wound to the back of his head and his death was ruled a homicide.

Investigators used surveillance and license plate readers to trace the Smart car to a U.S. Coast Guardsman who lived in northern Virginia with his wife, Chelsea Denise Perkins. GPS data from Dunmire’s phone placed him at an Airbnb in Cleveland that Perkins had rented. Witnesses in the park reported seeing a woman matching Perkins’s description that day and hearing a gunshot; Perkins’s DNA was later matched to samples from Dunmire’s body and a handgun recovered at her former Virginia residence was identified as the murder weapon. Perkins was arrested in December 2021 and later indicted on murder and firearms charges.

Did anyone in the Cleveland or Cuyahoga Valley area see the Smart car or the woman on March 5 or March 7, 2021?
