The man charged in a deadly attack on a Grosse Pointe interior designer has pleaded guilty to second degree murder.

David Corzilius, 49, now faces 30 to 60 years in prison. His sentencing is scheduled for November 22 at 10:30 a.m. 

Investigators say Daniel Clancy, 69, had just returned from shopping at Costco on March 6 when he was attacked in his home in Grosse Pointe Farms around 4:30 pm.

According to police, Corzilius demanded money from Clancy and then hit him in the face, bound his hands with duct tape and slashed his neck. 

Police say Corzilius was hired as a handyman to clean gutters and remove snow at Clancy's home.

Corzilius, a reported heroin addict who also suffers from bipolar disorder, claimed in court that Clancy pulled a knife on him before he began to assault the interior designer.
