MADISON, Wis. (AP) — The state Supreme Court says a man convicted in a decades-old homicide isn't entitled to DNA testing.

Police found Christopher Mohr dead in Grafton in 1982. A jury eventually convicted Jeffrey Denny and his brother, Kent, of killing Mohr. They were sentenced to life in prison.

Jeffrey Denny filed a motion in 2014 seeking DNA testing of evidence from the scene. A judge denied the motion but a state appeals court reversed him last year.

A divided Supreme Court ruled Tuesday that the judge correctly denied the testing request, saying the evidence against Jeffrey Denny was extensive and the idea that DNA tests might cause investigators or a jury to reject that evidence is just conjecture.

Denny's attorney, Keith Findley of the Wisconsin Innocence Project, had no immediate comment.
