MUSKEGON, Mich. (WOOD) — Three Muskegon County Sheriff’s Office detectives who worked on the Jeffrey Willis case have been honored as the Peace Officers of the Year.

Detectives Lisa Freres, Chad Petersen and Matt Schultz received the 2018 award from the Michigan Fraternal Order of Police.

“These three detectives compiled a large volume of information and presented a clear case that resulted in a conviction for first degree murder,” MiFOP President Mike Sauger said in a Thursday statement. “Their relentless effort and attention to detail helped make our communities safer.”

Willis was convicted last year of the 2014 murder of Rebekah Bletsch and earlier this year of murdering Jessica Heeringa in 2013.

It was decided earlier this week that the several remaining charges against Willis would be dismissed. In explaining his decision not to take those cases to trial, the county prosecutor noted Willis is already serving two life sentences without the possibility of parole and said “there is no reason to give him another stage or platform.”
