Saturday marks one month since the tragic fatal shooting of two Bristol police officers who were responding to a domestic disturbance call, and Bristol Mayor Jeff Caggiano wants to light the city blue in honor of them.

Caggiano is asking residents to put out blue lights on Saturday night in support of the Bristol Police Department. He is hoping to have 80% of the homes in Bristol lit blue.

The lights will honor Lt. Dustin DeMonte and Sgt. Alex Hamzy, two officers killed in a shooting on Oct. 12. The two officers responded to a call that night and were shot by a gunman. Another officer, Alec Iurato, was injured in the shooting and fired the shot that killed the gunman.

“A blue light on the outside of your home, or maybe even blue Christmas-type lights, a blue lamp inside a window, whatever you have that lights up blue,” Caggiano said.

He said the initiative started organically, with many homes replacing their outdoor lightbulbs with blue lights within days of the shooting.

Caggiano said about 20% to 30% of homes in Bristol had blue lights within a week of the shooting. This number has crawled up to about 40 to 50% now after he put out some videos on Facebook encouraging it.

The local fire department passed out about 300 blue light bulbs in the first week after the incident, Caggiano said. Local stores were running out of bulbs but many have restocked. Caggiano suggested residents buy some off the internet if needed.

The city also started the Bristol Police Memorial Committee, a subcommittee of the Bristol Police Commission established to honor officers who have died in the line of duty, earlier this month. The committee has not met yet but will sift through hundreds of suggestions for ways to memorialize the fallen officers, Caggiano said.

“That group is going to be taking the hundreds, literally hundreds, of ideas that we’ve gotten into a short-term, and more importantly, a long-term memorial,” he said.

Over $900,000 has been donated to the two certified funds supporting the families of DeMonte and Hamzy and the police department, Caggiano said. A Fund the First fundraiser has netted over $580,000 and the Bristol Heroes Fund has received in the high-$300,000 range, he said. Other fundraisers, like the Greg Hill Foundation, have donated more on top of that, he said.

One local initiative started by a couple, 43-year-old Rob Osenkowski and 41-year-old Lori Osenkowski, known for their yearly light decorations, the Lights on Rosewood, have raised over $24,000. The money they have raised will be split in three ways and donated to each of the families of the officers involved.

The Lights on Rosewood house, located at 111 Rosewood Drive in Bristol, is a yearly Halloween and Christmas-themed light show at the Osenkowski’s home. The couple has been running the lights for 12 years, first starting with Christmas and then expanding to Halloween over time. On the day of the shooting, the family decided to switch the lights to blue.

“They’re always there for us and when we heard what happened, as a community, it was our responsibility to now pick up and be there for them and their families,” Lori Osenkowski said.

The couple normally fundraises each year and donates it to a chosen family. They are doing that this year after Thanksgiving but are raising money for the families of the officers until then, Rob Osenkowski said. They have sold hoodies and 3-D printed commemorative ornaments and taken direct donations through their Venmo (@lights-on-rosewood).

The home will be lit in all blue on Saturday and Sunday from 5:30 to 9:30 p.m., Rob Osenkowski said. The family will also be permanently adding a police badge and two battle crosses to the display in honor of the fallen officers.

There will be a comedy show in the officers’ honor on Dec. 3 at the Bristol Polish American Club on Main Street in Bristol. Profits from the show will be donated to the families, according to the show posting.

Bristol residents have also planned a silent vigil in front of the Bristol Police Department station at 5:30 p.m. on Saturday evening.
