Police are searching for Jacobs-Royer's SUV, a 1998 Isuzu Trooper bearing a New York license plate number of GDD-8741 and a New York Jets spare tire cover.

Authorities are awaiting autopsy results, and Croizer declined to provide further details on the case, citing the ongoing investigation.

The Ulster County Sheriff's Office, the county's district attorney's office and State Police are assisting the investigation, Croizer said.
