Prosecutors say Lamoureux lived with O’Leary in Highland Park. He is accused of using a sharp object to fatally attack O’Leary on Nov. 21 at the residence.

“On November 21, 2021, at approximately 12:30 p.m., Highland Park police officers were dispatched to a residence in the 150 block of Candler Street in Highland Park for a reported stabbing. Upon their arrival, officers located the victim in the rear of the residence deceased with multiple sharp force injuries,” reads a statement from the Prosecutor’s Office. “It is alleged that Defendant Lamoureux fatally attacked the victim multiple times with a sharp object causing his death.”

O’Leary, 67, had a career in Detroit radio that spanned nearly 40 years.

“He was good enough to go from station to station, to CSX to W4. He built a reputation in this market as just a great lover of Detroit music and a Detroit personality,” former Detroit News TV and Radio columnist Jim McFarlin said.

Lamoureux was arraigned on the charges in 30th District Court. A probable cause conference is scheduled for Dec. 7.
