COLD SPRING HARBOR, N.Y. — The Long Island man accused of drowning his mother after the twp allegedly argued about him not taking his medication has plead not guilty in court Tuesday.

Denis C. Cullen Jr., 23, was arraigned Tuesday where he plead not guilty to murder in the second degree, Suffolk County District Attorney Thomas Spota said.

The charge in the indictment states Cullen is accused of murder in the second degree and that Cullen “on or about August 17, 2016, in Suffolk County with intent to cause the death of another person, caused her death by neck compression and immersion in water.”

Cullen told police in a recorded statement that he argued with his mother63-year-old Elizabeth Winn Cullen over him not taking his medication and he drowned her in their backyard swimming pool.

Things escalated and Cullen allegedly put her in a headlock and dragged her to the deep end of the pool. A violent struggle ensued and she drowned.

Cops say he took her body out of the pool and laid her beside the shed. He then went back to the house, showered and took money from his mother’s purse. Cullen hopped on the LIRR into Manhattan to see his sister in the city. There, he told her what he allegedly had done. She called their father who called 911.

Police responded and made the horrific discovery. Cullen later returned home while authorities were still there.

Prosecutors say Cullen does not have a prior record. They’re looking into his possible history of mental illness.

Cullen is in the county jail without bail. A court conference is planned for September 28.
