BRIDGEPORT — As the search for a missing 84-year-old woman reached its fifth day Thursday, law enforcement took to the sky and the grounds around a local park in the hopes of finding her.

The search, which was centered around Elton Rodgers Park, began around 1 p.m. There were searches in the area of the park and the woods north of the Trumbull mall, with helicopters searching by air for Teresa Zangrilli.

The 74-acre, largely undeveloped park has some woodlands, wetlands and steep slopes.

Later Thursday night, Scott Appleby, the city’s director of emergency communications and emergency management said police will be out again Friday.

He said police ask the community to review any surveillance footage and look around their property for any potential signs of Zangrilli. Anything found, and any sightings of her, should be reported to police immediately by calling 911.

Police started their search for Zangrilli, who has Alzheimer’s disease and diabetes, on Sunday night.

She was last seen near the Marshalls sign next to Price Rice on upper Main Street around 3:50 p.m. Sunday.

On Tuesday, search parties, a state police police canine unit and helicopters converged on the North End into the early evening in the area of Frenchtown and Old Town roads in search of Zangrilli on Tuesday.

On Wednesday, police said they expanded their search area to include the entire city of Bridgeport.

Anyone with information of Zangrilli’s whereabouts is asked to call 911 or the police department’s tips line at 203-576-TIPS.
