Detectives say the negative results from the Maskell DNA profile comparison means that the best hope for solving the case no lies with potential witnesses. Detectives are hoping that someone will come forward with conclusive information about the murder.
Sister Cesnik's body was found in a Lansdowne dumping area in January 1970. She was last seen in her Baltimore City apartment just before running errands in the Edmondson Village.
Maskell is not the first suspect whose DNA has been compared to the crime scene sample. Detectives have developed DNA profiles of about half a dozen suspects. None of the suspect profiles have matched.
The DNA profile from the crime scene was also placed into the FBI's Combined DNA Index System. There have been no matches fromthe scene with any DNA profile in the national database.
The murder of Sister Cesnik is the subject of Netflix's newest series, The Keepers. The series debuts Friday May 19.
