The adult was transported to a local hospital by Weston Fire Ambulance and has since been released.
In a statement shared by the Sudbury Police Department, Mason’s family remembered him as a fiercely loyal, loving, and empathetic friend who brought joy to those around him.
“A perfect son, grandson, nephew, and cousin — he loved his family more than anything (and his dog River),” the family wrote in a statement. “Mason was funny, goofy and crazy in all the right ways; he will be remembered for singing and dancing around the house with a wide smile on his face and a skip in his step.”
Mason enjoyed video games, sushi, swimming, skiing, running, and elaborate holiday decorations. His family said he also loved to draw and build stories with friends, he carried a notebook in his bag wherever he went.
The family said information about remembrances and a celebration of Mason’s life will be shared soon.
“Thank you to the countless friends, co-workers, and members of the community for your love and support,” the family said.
Sudbury police said the department is working with Sudbury Public Schools to provide support and resources to students, families, and community members affected by Mason’s death.
Chief McPherson encouraged anyone experiencing overwhelming grief or anxiety to seek support.
“Our Wayland community is grieving today, and thinking of those who lost so much as a result of this tragic accident,” Chief McPherson said. “I encourage anyone who is experiencing overwhelming grief or anxiety to talk to someone, reach out for help, and to remember that we are the strongest when we stand together as a community.”
