Blood found in the apartment of a man charged with killing a 17-year-old Wenatchee girl is a match to the victim, detectives with the Douglas County Sheriff's Department said Monday.
Detectives said the blood stain, which was not visible to the naked eye, was soaked through the carpet and padding on to the concrete floor below. A sample was sent to the Washington State Patrol Crime Lab in Cheney where a forensic scientist was able to determine the stain contained blood matching Cowell's specific DNA.
Investigators also found blood spatter and smears in the stairwell of a basement apartment below a salon owned by the suspect's mother. Cowell spent some nights staying in the basement apartment as well as the studio, police said.
