Edna Buchanan ‘elated’ DNA helped detectives find Pillowcase Rapist suspect
An arrest warrant later showed detectives believe he was the man who earned the moniker for using a pillowcase to cover the faces of dozens of his victims in South Florida. An FBI database helped detectives to catch their suspect. According to the arrest warrant, the rape kit of a 25-year-old woman who officers believe was his victim in 1983 was included in the FBI’s Combined DNA Index System. The first sample was from Koehler’s son Jan. 13, and detectives collected the second sample after following Koehler to a public area Jan. 16. Detectives sent the evidence to the Miami-Dade Police Department’s crime laboratory, where there was confirmation Jan. 17.
