Following the tragic death of Yarmouth Police Officer Sean Gannon, a Big Brother and mentor of three years, Big Brothers Big Sisters of Cape Cod & the Islands has released the following statement surrounding his involvement in the organization: “With heavy hearts, we mourn the loss of Sean Gannon and extend our condolences to his beloved family, friends and fellow officers. Sean was a dedicated police officer, a vibrant part of the Cape Cod community and a committed volunteer for three years as a Big Brother in our Bigs in Blue program.

Sean was the definition of a community-minded officer. He led by example and always gave of himself to others. Sean’s impact on his Little Brother over the past three years has led him to want to follow in Sean’s footsteps to become a police officer as he grows up. This tragedy has left a hole in the lives of so many, as well as the fabric of the Cape Cod community.

 As a mentor, Sean shared his wisdom, sense of adventure and passion for life with his Little Brother. At this time, we will not be offering any information on Sean’s Little Brother or his family. We are in touch with them currently offering our condolences and support as they too grapple with yesterday’s tragic events and the loss of a man they consider part of their family.

 We will carry Sean’s legacy with us from this day forward and will look to honor the ultimate sacrifice he has made for our community.”

 JR Mell, Regional Director, Big Brothers Big Sisters of Cape Cod and the Islands
