WATERFORD TOWNSHIP, Mich. -

It has been eight years since Kenneth Kanehl Junior and Pamela Barnes were found murdered in their Waterford Township home.

The two were each shot multiple times in the house on Brunswick Boulevard.  Eight years later, a new appeal is being made for information that might help solve the crime.

Kenneth's mother, Jessie Kanehl made an appeal.

"One day our justice will come and our family will finally get some kind of closure. I would not want my loved ones to give up on me it this happened to me, so how can I give up on Kenny and Pam," Kanehl said.

Kenneth Kanehl said he knows somebody has information that help find his son's killer.

"At least one person has knowledge of what happened and they are probably afraid to come forward but the truth will set you free," Kanehl said.

Investigators and family members do not know the motive behind the shootings.

Kenneth Kanehl Junior's daughter was 15-years-old when her father was killed.

Pamela Barnes had a 13-year-old daughter at the time of the killings.

Jessie Kanehl delivered a message to whoever committed the crime.

"To the person or persons who did this heinous act of cowardice, you'll never feel peace until you are caught and answer for your actions that you perpetrated that night," Kanehl said.

Crime Stoppers of Michigan has increased the reward for information that would lead to an arrest in the case. Tips can be called in to Crime Stoppers at 1-800 SPEAK UP.
