UPDATE: Police say blood found in Wilson’s apartment is a DNA match with Cowell.Back in February, 17-year-old Mackenzie Cowell was captured on surveillance tape getting into her car and leaving the Wenatchee beauty school where she was a student. It was the last time she’d ever be seen alive. When her body was recovered four days later, 20 miles south of town on the banks of the Columbia River, investigators determined that she’d been beaten, strangled and stabbed in the neck. Now, more than eight months after she was killed, police have made their first arrest.Mackenzie Cowell was a popular member of Wenatchee High’s Apple-Ettes dance team before she disappeared.Christopher Scott Wilson was arrested earlier today on suspicion of second-degree murder after a DNA test allegedly linked him to the scene of the crime. Wilson, 29, was Cowell’s classmate at the beauty school and reportedly left at the same time that she did the day she disappeared.Like all the other students, Wilson gave police a voluntary DNA sample. Two weeks ago, cops say a state crime lab report came back with a match on a piece of duct tape near where Cowell’s body was found. Cowell’s blood was also reportedly found on the same piece of tape.Investigators are still serving search warrants and thus far haven’t offered an explanation for why they think Wilson may have killed Cowell.
