LAKEWOOD, N.J. >> A toddler whose body was found inside a septic tank behind her home, just hours after being reported missing by her mother, died of accidental drowning, an autopsy showed Tuesday.

A preliminary investigation found "no indication of foul play or trauma," Ocean County Prosecutor Marlene Lynch Ford said.

The 2-year-old victim, identified by authorities only by the initials J.C., was reported missing by her mother, Marina Matias, shortly before 5 p.m. Monday. She had been playing in the yard with her four siblings.

Search teams quickly found a 3-foot-wide hole in the yard that led to a septic tank, and the Public Works Department was called to pump water from the tank. The girl’s body was found inside it around 7:30 p.m.

On Tuesday, toys were strewn about the yard of the ramshackle property, and the front door of the small house sat wide open. Police tape cordoned off the area where the top of the tank had been covered with dirt. The tank sat just a few feet outside the back door to the home, next to an outbuilding.

Public records listed the property’s owners as Catherine and Thomas Feeks of Sunnyside, N.Y. A message left on their phone listed under their name was not returned.

A man who said he has rented a room in the house from Matias and her husband said he was surprised that the opening to the septic tank was big enough for the girl, whom he called Jenny, to slip through.

The man, who spoke on the condition of anonymity because he said he feared retaliation, said the family is from the Mexican state of Puebla.

Neighbor Richard Castelluci, who has lived next door for nine years, said he thought the family had now abandoned the house. He said it has been rented out to families with children, like other houses in the area.

"It’s so sad, you know, you can’t bring the kid back," he said.
