WESTPORT — An investigation to a fatal fall during a roofing job in December has lead to the arrest of a Stratford contractor for not having a license.

Nelson Turcios, 51, was arrested Thursday on a charge of not being registered as a home improvement contractor.

At around 1 p.m. Dec. 4, firefighters and Emergency Medical Services responded to a Norwalk Avenue address on a report that two workers fell off a three-story roof. The workers had been doing repairs and there was scaffolding at the house, which is near Compo Beach.

First responders found one of the fall victims, Juan B. Rodriguez, 29, of Stamford, dead on the scene. The other worker was seriously injured.

Detectives determined Turcios was the contractor for the roofing job.

“Through a check of the Connecticut Department of Consumer Protection, detectives found that Turcios was not currently registered with the state of Connecticut as a Home Improvement Contractor,” the Westport police report said. “Based on the fact that Nelson Turcios did not have a contractor license, a warrant was submitted to Norwalk Court for his arrest.”

On Thursday, Turcios turned himself in and was released after posting a $10,000 bond. A Lexis database search indicated that Turcios had a home improvement contractor license from Dec. 1, 2004, until it expired on Nov. 30, 2006.

Meanwhile, OSHA and Westport police continue to investigate the circumstances of the accident and what caused the two men to fall from the roof.
