CENTRAL ISLIP, N.Y.—A suburban New York man drowned his mother in the family’s backyard pool after she argued with him because he wasn’t taking his medication, prosecutors said.
Denis Cullen was arraigned Thursday in Suffolk County on a charge of second-degree murder.
Newsday reports that the 23-year-old Cullen pleaded not guilty to killing his 63-year-old mother, Elizabeth Cullen. Bail was set at $5 million cash or $8 million bond.
Assistant District Attorney Robert Biancavilla said Cullen confessed to drowning his mother in the family’s swimming pool on Long Island on Wednesday.
