“It’s tragic to have something like this happen, and my thoughts are with the family and friends of the young man,” said Amesbury Mayor Kassandra Gove. “Our chiefs confirmed that a summertime water rescue hasn’t happened at Lake Gardner Beach in decades, though they are trained for them. I want to thank our Police and Fire Departments for everything they did to try and save the boy. This is not the outcome we wanted, but they deserve a lot of credit for going above and beyond in the call of duty. Officer Ronnie Guilmette put his own life in danger to search for the boy and didn’t think twice about it. Thank you to both teams for your efforts.”
