Police in Massachusetts are looking for a 59-year-old woman who vanished on Super Bowl Sunday just hours before she was set to host friends for a party.

Two concerned guests called police, NBC affiliateKPRCreported, and one day later, the Gloucester Police Department issued apublic pleafor help in finding the mother of three.

Gloucester Chief of Police Ed Conley told the outlet that Flynn spoke to her son around 4 p.m. on Sunday, and told him she was going for a walk.

She was last seen around 4:30 p.m., possibly wearing a blue puffy jacket, police said.

“We’re working primarily under the theory that she did what she said she was going to do, which was go for a walk, and perhaps either got lost or had a medical incident,” Conley told KPRC.

Police havesaidthey have no reason to believe foul play was involved in her disappearance.

Flynn’s brother Brian, who lives in Bermuda, toldDatelinethat he was in California visiting his son when Flynn’s husband Rich called him and told him she was missing, perNBC News.

Flynn, a retired nurse, grew up in Gloucester, and currently splits her time between the city and Houston, where Rich is a radiologist.

Brian reportedly toldDatelinethat Rich was in Houston when his wife went missing, but immediately flew to the East Coast.

“They have a wonderful life and are just really happy,” her brother said. “It doesn’t make sense that she would just walk away.”

He also praised his sister as “the most caring and selfless mother, friend and sister,” and said two of her adult children are away at college, while the other lives in New York.

Anyone with information as to Flynn’s whereabouts is asked to call the Gloucester Police Department at 978-283-1212.
