WOODROW (WABC) --The suspect in a deadly Staten Island home invasion is undergoing a psychiatric evaluation at Bellevue Hospital Tuesday after police say he fatally stabbed 67-year-old Peter Gialluisi.
Gialluisi's wife was stabbed in the neck and back and remains in the hospital.
Twenty-year-old Dante Viggiano has been charged with murder, attempted murder, burglary, criminal mischief, possession of a weapon and false impersonation in connection with the vicious home invasion that rattled the Woodrow neighborhood, where crimes of this nature rarely happen.
Authorities say 66-year-old Vincenza Gialluisi fought to protect her disabled husband from the knife attack in their home on Venus Place. She then ran screaming to a neighbor for help.
Peter had difficulty walking and needed a walker to get around.
The couple had surprised the intruder when they returned from a birthday party in New Jersey.
"Terrible, it's frightening, it's a terrible situation," neighbor Teresa Parenti said. "We live around the corner. It's scary."
Viggiano walked into a hospital Monday morning with defensive wounds. He was promptly taken into custody.
