James Krauseneck, now 70, received the maximum sentence for killing his wife, Cathleen Krauseneck, "with an ax while she slept in her Brighton home in 1982," Monroe County District Attorney Sandra Doorley said in a Twitter post announcing the news.
"[W]e do not give up on victims," she wrote. "We will do everything in our power to secure justice, even 40 years later."
The story of Cathleen Krauseneck's death, which became known as the "Brighton Ax Murder," was later turned into a Netflix special, "Things Heard & Seen."
Krauseneck was convicted in September of second-degree murder for the February 1982 slaying in Brighton, New York, a suburb of Rochester located roughly 85 miles west of Syracuse.
Brighton Police officers discovered Cathleen Krauseneck on Feb. 19, 1982, in the family’s Del Rio Drive home, dead from "a strike in the head with an ax while she slept," officials said. Officers located her lifeless body in her bed, the office said.
The district attorney’s office reviewed the case with renewed vigor in 2015 with the help of the FBI, the Brighton Police Department and famed forensic pathologist Dr. Michael Baden, who is also a Fox News contributor.
A grand jury indicted James Krauseneck in November 2019, after investigators determined James "moved away and went on with his life" after killing his wife, Doorley said.
