BILL RITTER: A woman and a boy found dead in a pond. The mystery tonight-- how did they die, and why?
- It happened in the Morris County town of Boonton.
BILL RITTER: Eyewitness reporter Lucy Yang, live at the tragic scene for us tonight with the latest. Lucy?
LUCY YANG: Well, that's right, this is such a shocking loss, coupled with so many questions. How did a 35-year-old mother and an 11-year-old boy drown here tonight, and why was the mother's six-year-old son left behind? He's the one who called for help.
The Boonton gazebo, so picturesque in the local park, tonight gave light to the grim and heartbreaking discovery. The bodies of a 35-year-old mother and an 11-year-old boy were pulled out of these frigid waters. This is the upper pond by the waterfall.
ROBERT CARROLL: A canvass of the area revealed that a female adult, approximately mid-30s, and a male child, approximately 11 years old, were found in the water at the top of the waterfall that the river goes into.
LUCY YANG: The alarm was sounded shortly after 5:30 Tuesday night, when a six-year-old boy in the area called, frantic about his mother. Police responded. Newscopter 7 was above.
We're told they found footprints leading them to the water. An hour later, the Boonton Water Rescue Team recovered two bodies by the top of the waterfall where the current apparently carried the mother and the young boy. Authorities not yet confirming the relationship of the 11-year-old child.
ROBERT CARROLL: This is under active investigation by the Boonton Police Department-- Detective Bureau, the Sheriff's CIS Unit, as well as the Morris County Prosecutor's Office Major Crimes Unit.
LUCY YANG: As authorities towed a Nissan SUV from the scene, locals tell us drownings happen here occasionally, but a wintertime drowning is especially shocking. And the fact that a child was involved, even more chilling.
ROBERT CARROLL: It's obviously a very sad day when children are involved in this type of situation. It's a horrible, horrible situation. And, you know, our deepest condolences go out to the family.
LUCY YANG: Again, at this hour we are waiting for authorities to release the names and the relationship of the two who died, and of course, an explanation for this terrible family tragedy. We're live--
