A home invasion that left one man dead and another wounded Friday was drug-related, Genoa police said.

Two Schaumburg men, Michael T. Kappa, 30, and Jason Middlekauf, 34, forced their way into the home of Michael Mason, 32, of 702 John Court, with a gun at about 10:20 p.m.

Mason then wrestled a nine-shot .22-caliber revolver away from one of the men and shot Kappa in the head and Middlekauf in the abdomen.

Kappa was taken by ambulance from the scene, but died early the next morning from his injuries.

Middlekauf left the scene in a vehicle and was later found at a McDonald’s near the intersection of Illinois routes 23 and 72 after he called for an ambulance on his cell phone. He is currently recovering at Kishwaukee Community Hospital, 626 Bethany Road.

Police conducting an investigation of Mason’s home later found 100 pounds of marijuana and $17,000.

Mason was charged with possession of marijuana under $5,000 and possession of marijuana with intent to deliver.

The home invasion was an attempted drug ripoff, said Genoa Police Chief Pat Solar, although police have not established a link between the two Schaumburg men and Mason.

“He wasn’t dealing in the neighborhood,” Solar said. “He was what we refer to as a wholesaler.”

Solar said wholesalers receive large quantities of drugs, break it into smaller portions and then transport it back to towns.

Mason has 11 previous drug-related arrests, Solar said.

The value of the marijuana found at Mason’s home was slightly under $300,000, he said.

The investigation into the marijuana is being conducted by the the North Central Narcotics Task Force.

The shooting is under investigation by the DeKalb County Major Crime Task Force, although no related charges are expected to be filed against Mason.

Some of Mason’s neighbors described him as extremely secluded, while others said he was friendly and helpful.

One neighbor, who wished to remain anonymous, said they were watching television the night of the shooting when they heard sounds like a car door slamming, unaware that they were gunshots.

They expressed concern over what they said was a violent incident in an otherwise quiet neighborhood.

“If these guys had come to our house by accident, what could have happened?” one neighbor said.
