JANESVILLE — The rural Browntown man charged in the fatal shooting of a man dating his ex-girlfriend is being held on a $500,000 cash bond while his competency to stand trial is evaluated.

A Rock County judge ordered the competency evaluation of Lucas Eugene Stuhr, 39, at the request of Stuhr’s defense attorney, noting concerns about Stuhr’s mental health and risk to self-harm. A hearing on that evaluation is set for Feb. 20.

According to the criminal complaint, Stuhr said he “blacked out” before 41-year-old Clifford A. Grice was shot in the head on Jan. 23 outside Grice’s home in Janesville, and Stuhr’s next memory is of fleeing the scene.

Stuhr was arrested later the same day after leading Green County deputies and a Monroe Police officer on a high-speed chase across the county, according to the Green County Sheriff’s Office. The Monroe officer spotted Stuhr’s vehicle on the outskirts of the city and followed it westbound on Wisconsin 11 to Stuhr’s residence east of Ullom Road in Cadiz Township.

The chase then continued through a snow-covered field and back east on Wis. 11 toward Brodhead. According to Sheriff Jeff Skatrud, Stuhr eventually stopped and surrendered himself after reaching a dead end in the Crazy Horse Campground and mobile home community outside Brodhead.

“The evidence in this case on the homicide is one of the strongest I’ve seen in our office,” said prosecutor David Jon O’Leary at Stuhr’s initial appearance in Rock County Circuit Court. The evidence includes an eyewitness account, home-surveillance cameras and an admission from Stuhr that, up until he blacked out, he did everything as the witness reported, O’Leary noted.
