(Scroll down for video) A missing New York toddler, was found buried after her mother did not tell anyone of his death for 2 years, according to police.
A routine child welfare investigation led to the discovery on Saturday, of a child's body buried in the backyard of a house in Long Island.
State Police unearthed the remains in the dead of night, in a tidy house in Farmingdale, after being informed by the child's mother that he died two years ago. The circumstances of his death was not clear on Saturday.
The boy, Justin Kowalczik, was about 17-months-old when he died in the summer of 2010, police said. Authorities said the family never reported the child's death.
"It's absolutely a suspicious death and is being investigated as such," State Police Major Patrick Regan said. "We have no cause of death, and to our knowledge, there has never been a report of a child lost."
Investigators were trying to determine how the child died and why the family kept it secret.
Agency officials of Suffolk County Child Protective Services initially went to the home on Wednesday, to check the health of one of the three children of the woman. They became concerned when the family could not explain the whereabouts of a child born in 2009.
That led to a police interview with the mother, Heather Kowalczik, who told them that the child had died shortly after the family moved to Farmingdale from Orange County, two years ago, Regan said.
On Friday, police investigated Kowalczik’s boyfriend, Robert Rodriguez, who is the father of her two older children, ages 6 and 9, but not Justin. As of Saturday afternoon, he had refused to answer questions, Regan said. "He is angry. He is not cooperating," Regan said.
Neither Rodriguez nor Kowalczik had been charged with any crime.
