Cottingham has claimed he was responsible for up to 100 homicides. He has been imprisoned since 1980. He is known as the “Torso Killer” because he allegedly cut off the heads and limbs of some of his victims, authorities have said.
Authorities believe Cusick left her job at a children’s dance school and then stopped at the mall to buy a pair of shoes when Cottingham followed her out to her car. They believe he pretended to be a security guard or police officer, accused her of stealing and then overpowered the 44kg woman. Cusick’s body was found on February 16, 1968.
The medical examiner concluded that Cusick had been beaten in the face and head and was suffocated. She had defensive wounds on her hands and police were able to collect DNA evidence at the scene. At the time, however, DNA testing did not exist.
Cottingham’s DNA was entered into a national database in 2016 when he pleaded guilty to a killing in New Jersey. In 2021, police in Nassau County began running DNA tests again on the cases involving the slain women and came up with a match to Cottingham.
Cottingham was working as a computer programmer for a health insurance company in New York at the time of Cusick’s death.
The other four women Cottingham confessed to killing on Monday were slain in 1972 and 1973.
Donnelly said that when detectives questioned Cottingham in prison, he provided information about those four cases that only the killer would know.
