A task force made up of /*NYPD*/, /*Drug Enforcement Administration*/ and /*Immigration and Customs Enforcement*/ officials and /*New York State Police*/ descended on the property this morning.
They began digging around 8:00 Monday morning along the Hudson River and near Palisade Avenue and Spaulding Lane in /*Riverdale*/.
A tip on an old homicide case, maybe a decade old, led investigators to the location inside /*Alder Brook Park*/.
Sources tell /*Eyewitness News*/ that agents are looking for a body that may be buried here.
The unusual activity startled those who live nearby and frequently use this park.
"I mean, it's upsetting to find that there may be a body buried down there," Margie Gayton said.
Dogs brought in to help with the search apparently smelled something, but more than 5 hours of digging turned up nothing.
Agents taped off the park to visitors and suspended the search for the day.
