HACKETTSTOWN � The phone of a missing Hackettstown woman was last used a little before 1 p.m. on Tuesday, according to the Hackettstown Police Department.

Through phone records, the department was able to determine that 24-year-old Krysten Mendez's phone was used in the Briarwood, Queens, N.Y., area at 12:43 p.m.

�We don't know if she is still in that area or if she has moved on,� said Sgt. Darren Tynan.

�It's still up in the air where she might be.�

Mendez was last seen at about 10:30 a.m. Sunday at her residence on Sharp Street in Hackettstown, according to police. She is described as 5 feet, 4 inches tall and weighing 194 pounds. She was last seen wearing a black T-shirt, red shorts, a silver ring on each hand and carrying two black/white duffle bag-type purses.

Tynan said that based on the information the police have on Mendez, her disappearance is odd.

�She does have a mental disorder but I can't disclose what that is,� said Tynan. �Due to that mental impairment, we don't want anybody to approach her� if she is seen.

The police department has no information about her previously exhibiting violent behavior, he said. But �with her mental impairment, it raises the stakes.�

Anyone with information that can assist in locating Krysten Mendez is asked to call 911 or the Hackettstown Police Department at 908-852-3300.
