Gwinnett County police Monday were investigating a weekend home invasion robbery and shooting that left a man dead.

The incident happened around 4:30 a.m. Saturday in the 3100 block of Park Colony Drive near Norcross.

Responding officers found Clifford Hogan, 38, unresponsive, lying face down next to his bed, according to Gwinnett police Cpl. Edwin Ritter.

Ritter said Hogan and his girlfriend, 39-year-old Christine Morris, “were lying in bed when two masked males entered the bedroom, armed with a pistol and rifle, demanded money and shot Mr. Hogan.”

After shooting Hogan, the men left, taking with them the victim’s cell phones, marijuana, $1,400 cash and Morris’ purse.

Ritter asked that anyone with information call investigators at 770-513-5300.
