A man who confessed to a 46-year-old Back Bay murder has pleaded guilty to the horrific cold case.
John Irmer, 71, entered a guilty plea for first-degree murder, which comes with a mandatory life sentence, according to the Suffolk District Attorney’s Office.
Irmer walked into an FBI office in Portland, Oregon, in 2023 to confess to killing a red-haired woman he’d met around Halloween in 1979 at a skating rink in Boston.
According to the DA’s office, Irmer told the FBI that after the meeting he’d walked into an apartment on Beacon Street that was under renovation with the victim, who turned out to be 24-year-old Susan Rose. Once inside, he said picked up a hammer, hit Rose on the head with it, killing her, then raped her. The next day, Oct. 30, Irmer said he left the state the next day for New York, while a construction crew found Rose’s body and a lot of blood.
Rose had been planning on dressing as “Dracula’s helper” for Halloween, borrowing a cape from a friend that she was wearing at the time of her death, according to a Herald article published the day after she was found.
A Boston Police detective described the killing as one of the most “vicious” he’d ever seen, telling Herald reporters whoever did it was a “real psycho.”
Another man had been tried for Rose’s murder a few months after the crime took place and was acquitted. In 2005, police reexamined evidence in the case and made a DNA profile from sperm found on a broom at the crime scene. Investigators found the DNA could not have been from the defendant in the first trial, the DA’s office said.
The FBI in Oregon reached out to Boston Police, who flew detectives across the country to interview Irmer. He told them that after becoming sober and finding religion during a prison stint in California for another killing, he felt he needed to confess to Rose’s murder.
During the interview, Irmer told police detailed information about Rose’s killing and confessed to another murder that took place in the South. According to the DA, investigators are also investigating that case.
In court Monday, Rose’s sister gave what the DA called an “emotional” impact statement, holding a photo of Rose when she was a first-grader.
Rose’s sister said she went by the nickname “Susie,” and was “caring, intelligent, adventuresome, and curious.”
“Now we know that my sister’s life was taken by John Irmer, but he also ruined the lives of my parents and me,” she said.
“The answers for Susan Rose’s sister and friends finally came today, though after a very long and sad period of time,” Suffolk DA Kevin Hayden said in a statement. “I hope other families affected by John Irmer’s murderous behavior find similar answers.”
