Three-year-old twin boys with autism drowned Wednesday morning in a Melville pool, Suffolk County Police said.
The drownings at the Holly Court home appeared to be accidental.
Law enforcement officials said the boys' mother woke up and did not see the children in their room. She found Nicholas Aurilia floating in the inground pool and pulled him out of the water. He was not breathing and his mother began to perform CPR on him, police said.
The fire department eventually found the second boy, Anthony Aurilia, still in the pool, which was murky and difficult to navigate.
The boys apparently got out through a back door. A five-year-old boy in the house was unharmed.
They were rushed to Plainview Hospital, where they were pronounced dead. Police said an autopsy will be performed by the Nassau County Medical Examiner.
The house changed hands late last year to a corporate owner, and officials said some work was done on the pool area this spring.
Town officials confirmed the house had a pool alarm and fence, all of which complied with local code.
