Connecticut police were conducting a manhunt Friday after a veteran Norwalk police officer was fatally shot while investigating a “suspicious incident.”

According to Police Chief Harry Rilling, the dead officer was Matthew Morelli, 38, an 11-year veteran of the department who was honorably discharged from the Marines after serving as an intelligence analyst, the Boston Globe reported.

The shooting occurred shortly after 12:30 a.m., when Morelli stopped to investigate suspicious activity in a secluded parking lot on Lubrano Place in south Norwalk.

"The uniformed officer was on patrol and had stepped out on Lubrano Place to investigate suspicious activity to the rear of the parking lot," Lt. Paul Resnick, the police department representative, said, according to Fox News.

"It's a shock and tragedy anytime you have an officer killed in the line of duty," Resnick added.

No details about a possible suspect have been released because the investigation is ongoing.

Police in search for traces blocked several streets near the shooting scene on Friday morning. In addition, several area departments are assisting and police helicopters from Westchester County, N.Y., and New York City were being used.

This is first Norwalk officer killed in the line of duty since Officer Marco Carias was killed March 20, 1982.
