STOCKBRIDGE, Mass. — An off-duty Great Barrington police officer died early Friday morning after his pickup truck hit a tree on Prospect Hill Road in Stockbridge.

Stockbridge Police Chief Darrell Fennelly said 25-year-old Ryan A. Storti of Muddy Brook Circle was pronounced dead at the scene of the crash, which was reported shortly after 2 a.m. According to a statement from the Great Barrington Police Department, Storti was alone and on his way home when he lost control of his truck and struck a tree on the side of the road.

The investigation is being conducted by members of the Stockbridge Police Department with assistance from the Massachusetts State Police Collision Analysis and Reconstruction Section.

"Officer Storti was a wonderful young man and police officer," Great Barrington Police Chief William Walsh said in a statement. "He was everything we wanted in a police officer and was part of our future. We're all struggling right now as we also try to support Ryan's family. Please keep them all in your thoughts."

Storti, a 2008 graduate of Monument Mountain Regional High School, had been a reserve officer in Great Barrington until being appointed to a permanent position in 2015. He graduated from Berkshire Community College and from the Western Massachusetts Police Academy in Springfield.

"Officer Storti was a rising star for our police department. I am devastated to learn of his sudden death," Town Manager Jennifer Tabakin said in a statement. "This is a tragedy and an enormous loss for the Police, our Town and the entire community. Our hearts go out to Ryan's family and all who loved him and worked with him every day in public service. He will forever be in our thoughts and prayers."

Funeral arrangements are pending.
