The 39-year-old Mashini was found Saturday night, Aug. 3, more than a day after she'd been reported missing, Paramus police said.
Police did not disclose Mashini's condition, nor did they say where she was found.
Mashini had last been seen on Friday, Aug. 2 around 1:30 p.m., police said, who did not release her condition.
Daily Voice's messages to law enforcement officials placed Saturday night and Sunday morning, Aug. 4 had not been returned as of 11:15 a.m.
On Saturday morning, prior to Mashini's discovery, Paramus Police Chief Robert Guidetti said officers thoroughly searched the local mother's home and known "hangouts."
They've checked local hospitals, shelters, and other relevant locations for any recent admissions or sightings, and detectives have interviewed several people who were in close contact with Mashini, Guidetti said.
"Each provided valuable insights into the person’s recent activities and state of mind," the chief said. "Despite their cooperation, no concrete leads emerged that would indicate Heather’s. We will continue to monitor any new leads or information that may arise and will provide updates as necessary."
