The standoff that brought a mass of police to New Egypt Tuesday has ended, with one person in custody and his wife dead of stab wounds, authorities say.

Arthur Haskoor, 50, is accused of killing his wife of 20 years and threatening to kill police, according to the Ocean County Prosecutor's Office. Charges are pending.

School officials received information about a domestic dispute at 120 Evergreen Road in the New Egypt section of Plumsted at about 10 a.m, officials said. Both New Egypt High School and Middle School are across the street from the home.

School officials immediately called 911and members of the Plumsted Township Police Department were dispatched, the prosecutor's office said.

Once there, officers found a deceased woman — later identified as 48-year-old Susan Haskoor — dead of stab wounds in the driveway, the prosecutor's office said.

The officers continued to the home's front entrance and found a note on the front door saying there were guns inside, and the occupant would kill them, the prosecutor's office said. The Haskoors' son later confirmed to police there were at least six weapons in the home, the prosecutor's office said.

Authorities used resources from Ocean County Northern Regional SWAT Team, Ocean County Prosecutor's Office, Plumsted Township Police Department, Ocean County Sheriff's Department, and the New Jersey State Police to secure the home and establish a permitter. At about 2:30 p.m, a camera-equipped robot entered the home and found Arthur Haskoor unresponsive, authorities say.

The prosecutor's office said it didn't have any information to release on Arthur Haskoor's condition. He was airlifted to Jersey Shore Medical Center.

The couple had been married for 20 years with two male children, ages 17 and 18, according to the prosecutor's office.
