NORWALK -- A 72-year-old New Canaan man, who allegedly struck and mortally injured a Norwalk motorcyclist last summer, was arraigned for the first time on charges of vehicular homicide and failing to obey a stop sign at state Superior Court in Norwalk Tuesday.

John McCaffrey, of 74 Sleepy Hollow Road, New Canaan, appeared with his attorney Frank Bevilacqua, who continued the case to March 29. No plea before Judge Maureen Dennis was made on the charges.

After a near five-month investigation, a warrant was signed for McCaffrey's arrest and he turned himself over to New Canaan police on Feb. 18.

"These are tragic circumstances all around and we are working to resolve the issues," Bevilacqua said.

The accident occurred on Sept. 13 at almost 5 p.m. on a clear and sunny day as Robert Jacob of Norwalk was traveling southbound on Smith Ridge Road, McCaffrey's three-page arrest affidavit said.

Jacob, 55, was turning his purple 2001 Harley-Davidson 883 left onto Canoe Hill Road.

At the same time, McCaffrey in his 2001 red Dodge Durango traveling west on Canoe Hill Road, was turning left onto Smith Ridge Road, his arrest affidavit said.

Two witnesses told police that while Jacob was in the process of making a left onto Canoe Hill Road they saw him get run over by the Durango. There is a stop sign for those traveling west on Canoe Hill Road before proceeding onto Smith Ridge.

At the scene and in a later interview, McCaffrey told police that he saw the witnesses' vehicles, but did not see the motorcycle, the affidavit said.

McCaffrey offered no other explanation for why the accident took place, the affidavit said. The brakes were checked on the Durango and Harley-Davidson and each were operational.

The headlight and the left turn signal on the motorcycle were both illuminated at the time of the accident, the affidavit said.

Jacob remained hospitalized in the intensive care unit of Norwalk Hospital until Sept. 19, when he was pronounced dead, the affidavit said.
