Clarence Marcus Tappendorf (July 16, 1927 – January 6, 2008) was an American murderer who murdered two young women in the Milwaukee area in 1966 and 1971.[2]

In 1966, 19-year-old Diane Olkwitz was murdered at her workplace in Menomonee Falls, Wisconsin, which is located in the Greater Milwaukee area. Olkwitz was stabbed over 100 times and her clothes were disheveled. Five years later, in 1971, the body of 15-year-old Terri Erdmann was discovered in a field on the northwest side of the City of Milwaukee. Erdmann was nude from the waist down, bound with twine and stabbed roughly 60 times.[3]

Both women had been brutally stabbed numerous times. The murders were not immediately linked, and a suspect was not identified for either case and the murders of both young women remained unsolved for over 50 years.[4]. The murders of both woman were not immediately linked together.

In 2022 the Milwaukee Police Department, the Wisconsin Department of Justice, and the FBI linked both crimes together via DNA evidence and that DNA evidence was submitted to Othram for genealogical analysis. Othram managed to extract the information from the DNA and gave it to the FBI's forensic genealogical genes team for new clues. Armed with these new leads, investigators met with genetic relatives of the possible subject and were able to obtain DNA samples from the subject's brother and son confirming a link to the subject, who was identified by law enforcement officials in October 2023 as Clarence Marcus Tappendorf. Tappendorf’s remains were exhumed to definitively link him to the crimes using DNA evidence, and while that link was established, Tappendorf cannot be prosecuted, as he died of natural causes in 2008.[5] [6]
