Thirty years ago today, a Connecticut state trooper was struck and killed on I-95 in Greenwich.

Trooper Jorge Agosto, who was 27, was working on one of the busiest traffic days of the year — the day before Thanksgiving — Wednesday, Nov. 22, 1989.

“Although three decades have passed, time has not diminished our loss,” state police posted on social media.

Although Agosto worked in the Troop L barracks in Litchfield, the two-year veteran was assigned that day to patrol a busy stretch of I-95 before the holday.

On that day, Agosto pulled his cruiser behind another trooper’s Crown Victoria to assist in a motor-vehicle stop. While Agosto was walking along the shoulder of the highway, a motorist veered off the road and struck him from behind.

The driver of that car was Michael Murphy, a New York City stockbroker, who was on his way to Cape Cod to have Thanksgiving dinner with his family. Murphy was subsequently charged with manslaughter in Agosto’s death.

An investigation determined that Murphy had a diabetic seizure at the time of the accident. He was found to be suffering from hypoglycemia, a condition brought on by low blood sugar that caused dizziness, confusion and blackouts.

John Rodia, the trooper who was working with Agosto at the time, would later face his own demons. He developed an addiction to OxyContin after seeing Agosto killed and later got into a bad car accident.

On the Officer Down Memoral Page, Rodia wrote on the 20th anniversary of Agosto’s death:

“It's difficult to believe that a score has passed since that awful day in Greenwich. I never had the chance to thank you for protecting me that day, but I have lived with your memory since.

“While I do truly wish that I could have helped you I know that's not the way it was. I used to question why I was there, but now I know that I am both proud and grateful to have been with you and to have known you as a Trooper and a friend. Thank you Jorge and know that I will never forget.”

Agosto had served with the Connecticut State Police for two years and was assigned to Troop L. He was survived by his wife.
