The jury's verdicts capped more than 37 hours of deliberations over a four-and-a-half days in the Dutchess County Courthouse, in Poughkeepsie.

Gilleo, 33, of Hopewell Junction, N.Y., also was convicted on five counts of armed robbery, two counts of conspiracy, one count of perjury and two counts of arson.

A co-defendant, 30-year-old Mark Serrano, was convicted last year on 31 first- and second-degree murder charges, in addition to arson, robbery, conspiracy and perjury charges.

Gilleo and Serrano were accused of going to the Morey home on Route 82 in Fishkill and robbing Manuel and Tina of cash and cocaine, killing all five members of the family and setting fire to their house and car in an attempt to cover up the crimes.
