DETROIT (AP) -- A Jackson man who testified against two co-defendants in the slaying of a suburban Detroit hairdresser has been sentenced to 28 to 40 years behind bars.
Matthew Williamson pleaded guilty to second-degree murder in the death of 66-year-old Gary Gagnon of Livonia.
The 27-year-old Williamson testified last week in the trial that ended with 41-year-old Derek Worthy of Southfield being convicted of second-degree murder and home invasion. A separate jury found 27-year-old Senica Hale of Detroit not guilty.
Gagnon's disappearance was discovered when he failed to show for work in March at the Hair Emporium in Allen Park. His home had been burglarized. Gagnon's body was found a week later in a Detroit home.
Worthy faces up to life in prison when sentenced on Feb. 8.
