• Emma Tetewsky was found stuck in swamp mud after she'd been reported missing.
• Hikers called 911 and said they heard a woman screaming for help in a Massachusetts state park.
• Police said she might have been trapped there for at least three days.

A woman who had been missing for a week was found stuck in mud at a Massachusetts state park, police said.

Police said it is believed that she might have been trapped there for at least three days.

Emma Tetewsky, 31, was rescued at 6 p.m. on Monday after hikers called 911 and said they heard a woman screaming for help in a swamp-like area, authorities said in a statement. 

When Easton police officers arrived, they could hear Tetewsky but not see her, and used all-terrain vehicles and waded 40 feet through thick brush and swamp to reach her at Borderland State Park, south of Boston.

Tetewsky was found lying in a shallow area of the swamp in a fetal position. The sticky mud was knee-deep and it took several efforts to free her, The Enterprise reported.

She was dehydrated, sunburnt and had multiple injuries to her upper body, police said. per The Enterprise.

She was conscious and alert when she was found and was taken to hospital to be treated for non-life-threatening injuries, police said, per The New York Times.

Police  said at the time that Tetewsky did not have a cellphone with her when she went missing and that she had a history of struggles with her mental health, NPR reported.

"We want to thank all of the agencies that cooperated with us," Stoughton Police Chief Donna M. McNamara said.

"If it wasn't for the public helping us and giving us tips over the last five days, we wouldn't have been able to locate her. This is the best possible outcome," she added.

Tetewsky was reported missing last week after her family told police they had not seen her since Monday.

"So many times this type of story ends sadly and I didn't have much hope at all. I thought she would have already succumbed to the elements," Emma's father, Avran Tetewsky, told WBZ.

"It was traumatic to be stuck in the mud for as long as she was," her mother Barbara Zinaman said. "It's miraculous that they found her."
