Chase Kowalski, Age 7
Chase Kowalski loved to be outside riding his bicycle, running or playing baseball, according to his family and neighbors.
He competed in his first triathlon at age 6, according to his obituary. He was a Cub Scout, and was a "fun loving energetic boy that had a true love of life."
Kowalski's family "sends their prayers and thoughts to all of the families involved with this horrific event," the obituary said.
Just last week, he was visiting neighbor Kevin Grimes, telling him about completing — and winning — his first mini-triathlon.
"You couldn't think of a better child," Grimes said.
Grimes' own five children all attended Sandy Hook, too. Cars lined up outside the Kowalski's ranch home Saturday, and a state trooper's car idled in the driveway. Grimes spoke of the boy only in the present tense.
