A bicyclist was killed after a collision with an unmarked Norwalk police vehicle on Connecticut Avenue Monday night.

It happened at 6:07 p.m. at the busy intersection with Fairfield Avenue and Clinton Avenue. Manuel Bonilla-Gomez, 68, of Norwalk, was rushed to the hospital but did not survive.

Connecticut State Police are handling the investigation and released an initial report Tuesday afternoon. That summary said Bonilla-Gomez was riding south on Clinton Avenue and went through a red light at Connecticut Avenue and into the intersection where he was hit by an SUV driven by Detective Andrew Roncinske. The detective was heading east on Connecticut Avenue and had a green light, according to state police.

They said the detective’s unmarked vehicle was equipped with emergency lights, but there was no mention of whether they were activated at the time of the crash or where the SUV was headed.

Norwalk’s police chief initially said the detective was responding to a call when the crash occurred. A later update from the chief did not mention that. In the release, Chief James Walsh stated, “I ask that we all keep the family of Manuel Bonilla-Gomez, Detective Roncinske, and all those affected by this tragic accident in our thoughts and prayers during these most difficult times."

Roncinske has been with the department since June 2014. He’s now on administrative leave as is protocol.

Bonilla-Gomez was originally from Honduras but had been in Norwalk for 25-30 years, according to his son Mario Isaguirre. Isaguirre lives in New Jersey and learned the news about his father in a call from the hospital Monday night.

“I come in today. I’ve gotta go get a report from the hospital. My father's dead,” Isaguirre said, getting emotional. He had little information about what happened in the crash but had stopped at the intersection where it occurred to see the area for himself.

Isaguirre said his father rode his bicycle in the area all the time. He thought Gomez-Bonilla might’ve been heading home after stopping at the Dollar Tree in the area. Isaguirre described him as a good father who had a lot of people depending on him. He said Gomez-Bonilla had worked in landscaping but stopped as he got older. He also said his father had been planning to move back to Honduras.

Bonilla-Gomez’s loved ones have started a fundraising campaign, so he can be laid to rest in his native country.

A gas station and a cannabis retailer are located at the intersection where the crash occurred, but employees at both businesses said their security cameras don’t face the collision site and didn’t capture what happened.

There are traffic cameras at the intersection which may help state police are they continue to investigate. Anyone who witnessed the crash or the moments before it is asked to reach out to CSP Detective Nicholas Olivetti at nicholas.olivetti@ct.gov.

The crash shut down Connecticut Avenue for about seven hours.
