NEW YORK - A couple was being held Saturday on $500,000 bond after pleading not guilty to starving their 7-week-old son to death in a squalid home.

Matthew Mason weighed just 2 pounds when he was found dead on Easter Sunday in his Staten Island home, authorities said.

Joanne Fezza and Peter Mason kept little food on hand and subjected Matthew and his 5-year-old brother to “unsanitary, filthy conditions in the kitchen and bathroom,” according to an indictment filed Thursday.

Medical examiners concluded the infant had died of starvation.

Fezza, 42, and Mason, 46, were arraigned Friday on manslaughter and child endangerment charges.

If convicted, they could face up to 15 years in prison.
