The 24-year-old woman was taken to St. Joseph's Regional Medical Center in Paterson by a Fair Lawn Volunteer Ambulance crew just after 1:30 a.m. with stab wounds in the arm, leg and back, Sgt. Brian Metzler said.
The victim was stabbed at Sixth Avenue and Butler Street, responders said.
Metzler wasn't initially certain why she ended up at the Berdan Avenue ranch house, which records show is owned by an official with a law enforcement agency in another county.
A search for the assailant included area police and a K-9 unit.
