MASTIC BEACH (AP)— Two of five family members accused of keeping seven young children in a feces-strewn, filthy home on Long Island pleaded not guilty Friday to child endangerment charges.

Siblings April Hall and Eamon Hall were ordered held on $2,500 bail after entering the not guilty pleas. Their two sisters and father still awaited arraignment.

The five family members were arrested Thursday after police found the children, ages 2 to 13, in a Mastic Beach house without running water or heat, and littered with animal feces.

Suffolk County police said a foul odor greeted officers when they arrived in a working-class neighborhood, after being contacted by Social Services officials. Inside, police found clothes strewn about the floor, animal feces on floors, and soda bottles filled with urine.

Richard Hall, 61, his three daughters, Bernadette, 36, April, 27, and Krystal Hall, 21, and a son, Eamon, 23, were arrested on seven counts of endangering the welfare of a child. The children were placed in the custody of Child Protective Services.
