FALL RIVER, Mass. — A 40-year-old woman and mother, missing and considered endangered because of mental illness, was found dead Wednesday afternoon outdoors several blocks north of her North End home, police said.

Janet Marie Jimenez of Lindsey Street was missing since July 3 and found in an obscure area behind a commercial building, said police spokesman Sgt. J.T. Hoar.

“She’d been there longer than 24 hours,” Hoar said of the woman, based upon their observations.

He said their Major Crimes Unit, in combination with State Police, had continued an active search and saturated the area, and found the woman about 12:30 p.m.

The chief medical examiner’s office took custody of Jimenez.

An autopsy and toxicology testing will be done to determine her cause of death, Hoar said.

“At this time, it does not appear that foul play was a factor in Ms. Jimenez’s death, but this investigation remains open and ongoing pending results from the medical examiner’s office,” Hoar said in a press release late Wednesday night.

She suffered from bipolar disorder and numerous psychiatric issues and recently stopped taking her medications, according to police alerts during the past week.

Video footage also showed Jimenez “looked as though she was distraught ... walking aimlessly in the area,” Hoar said in a phone interview.

Her children, whom Hoar said were teenage and a little younger, were not aware of her medication information. She also had a brother who’s been actively involved in trying to find her.

She left her pursue and phone behind after leaving home, which was uncharacteristic, police previously said.

“Our condolences go out to the family. We wish we could have found her sooner,” Hoar said.

He said detectives searched door to door, combed train tracks, desolate and other areas and found her behind a commercial building he was not ready to identify. Police later cleared the scene.

He said the testing police seek could take months to furnish complete results.
