Hartford, CT – K-9 Roso, a highly trained patrol dog, has been retired following the death of his handler, Trooper First Class Aaron Pelletier, who was killed in the line of duty on May 30, 2024.
Pelletier was conducting a traffic stop when he was struck by an impaired driver who fled the scene. Roso, inside the patrol vehicle at the time, was unharmed.
Roso and Pelletier had worked together since graduating from the 223rd K-9 Patrol Class in December 2021.
Assigned to Troop H in Hartford, they quickly distinguished themselves in the field. Their teamwork led them to the State Police Tactical Unit, where they contributed to significant law enforcement efforts.
Over their time on patrol, they were responsible for multiple key finds, demonstrating skill and precision.
With Pelletier gone, Roso has transitioned from a life of service to one of companionship. He now lives with Pelletier’s wife, Dominique, and their two sons, Troy and Zachary.
No longer tracking suspects or securing crime scenes, he spends his time chasing chickens and playing ball in the family’s backyard.
Although retired, Roso’s role in law enforcement history has not ended. He has been accepted as the eighth foundation dog of Harlow’s Heroes, an organization that honors K-9 officers and their fallen handlers.
His induction ensures that his years of service and dedication will not be forgotten.
For the Pelletier family, Roso remains more than a retired police dog. He is a connection to the trooper they lost, a protector in his own right, and a reminder of the bond between an officer and his K-9 partner.
