A 43-year-old man, already serving life in prison without the possibility of parole, plead guilty in Genesee County circuit Court on Wednesday for the murder of a Genesee Township woman nearly 20 years ago.

Matthew Alder plead guilty to Second Degree Murder for the death on Wanda Muck with an agreement that he be sentenced to 20-30 years. The victims family was in the courtroom when the plea was entered.

On November 14, 1993, Alder abducted a 19-year-old Musk at knifepoint in the early morning hours from the One-Stop Gas Station & Market on Richfield Road. Her body was found later that morning.

DNA discovered at the crime scene and preserved for nearly two decades was used to link Alder - who had been convicted of a similar crime in Roseville in 1996 - to the homicide.

Genesee County Prosecutor David Leyton said he was "pleased we were able to provide closure to the victims family. They certainly waited a long time for justice to be served." Leyton also acknowledged retired Genesee Township Detective Gerald Parks "for his tireless dedication to this investigation" saying Parks "gave a significant portion of his life to finding Wanda Musk's killer."
