Handyman sentenced in murder of Grosse Pointe Farms interior designer

GROSSE POINTE FARMS, Mich. – A 49-year-old handyman who pleaded guilty to murdering a Grosse Pointe Farms interior designer was sentenced Tuesday to 30-60 years in prison for the stabbing death of Daniel Clancy.

David Corzilius pleaded guilty to second-degree murder and his plea came with a sentence agreement of 30-60 years in prison. The remaining counts were dismissed.

Corzilius, of Warren, was accused of slashing 69-year-old Clancy’s throat in his Grosse Pointe Farms home during an argument on March 6. Authorities said Corzilius demanded money, bound Clancy with duct tape and forced Clancy to point out valuable paintings he could steal. Clancy escaped the home while Corzilius was removing artwork. Corzilius ran after Clancy and stabbed him in the neck several times.

Clancy was left bleeding on the sidewalk and a passerby called 911. He died several days later, but was able to tell police the first name of his attacker before he lost consciousness.

Corzilius was tracked down to a hospital, where he was being treated for a heroin overdose. Police said he confessed to attacking Clancy during interviews. He was originally charged with assault with intent to murder, assault with intent to do great bodily harm, felonious assault, armed robbery, home invasion, unlawful imprisonment and larceny in a building.
