The 20-year-old Monroe woman killed in a major crash on River Road in Shelton over the weekend was the daughter of a Bridgeport police officer, officials said Tuesday.

Lily Pirulli and 31-year-old Adrian Miles, of Ansonia, were killed in a two-car crash that closed a stretch of River Road for about eight hours late Sunday night into Monday morning.

Pirulli was the daughter of longtime Bridgeport Police Officer Mario Pirulli. He has been on the city’s police force since October 1993.

A joint statement from the city and the police department on Tuesday offered thoughts and prayers for the officer’s family.

“We cannot begin to imagine the heartache their family is experiencing from this tragic accident,” the statement said. “The city of Bridgeport and the brothers and sisters of the Bridgeport Police Department are united in standing alongside our officer at this time and wish him strength and peace while we allow the Pirulli family space and respect their time of grieving.”

Pirulli graduated from Masuk High School and Miles attended Ansonia High School.

The two were among four people in a BMW that collided with a Toyota RAV4 around 11:30 p.m. Sunday near the entrance to Southbank Park in Shelton.

A 26-year-old Ansonia woman remained in critical condition Tuesday, while a 30-year-old Derby man was treated and released from the hospital. They were the other occupants of the BMW, police said.

The driver of the Toyota RAV4 was treated at the scene and released, according to authorities.

Sunday’s deadly crash remains under investigation by Shelton police.
