Nearly 100 days after a multi-agency police investigation spanned two counties and two states, New York state and local law enforcement this week announced the arrest of 10 people in connection to the “disturbing” slaying and kidnapping of a homeless man.

On May 20, 33-year-old Thomas P. Rath was reported missing from a homeless encampment in the city of Ithaca, New York State Police and the Ithaca Police Department said during a joint press conference Monday.

An investigation that began in May as a missing person’s case unearthed “a particularly disturbing and a heinous series of events which ultimately revealed the kidnapping and murder of Mr. Rath,” State Police Commander Major Jeffrey VanAuke told reporters.

Rath was “forcibly abducted from his encampment” on May 20, State Police Capt. Lucas Anthony said. The camp, known to locals as “the Jungle,” is behind a Lowes in the city, some 60 miles south of Syracuse near the Pennsylvania state line.

On Aug. 3, officials said, Rath’s remains were found buried in a shallow grave on state land in nearby Tioga County.

As of Tuesday, authorities had not released a motive in the case or said how they believe the man died.

Rath was a a father, a brother and a son, Anthony said. He joined Ithaca’s acting police Chief, Lt. Ted Schwartz, in expressing condolences to Rath’s family during the press conference.
