Bruce Pardo's house

MONTROSE -- Pictured to the left is the unassuming home where Covina massacre suspect Bruce Pardo lived.

Christmas decorations remain on display, which neighbors said he erected shortly after Halloween.

Neighbors, like most others who knew Pardo, say they are shocked the man they knew as friendly, gentle and helpful could be responsible for the killings in Covina.

A notice from the water department hung on the door, and the mailbox was overflowing with mail.

A Cadillac Escalade, which neighbors said belonged to Pardo, remained parked in the driveway.
