Marino was 70 percent disabled in his right knee and left shoulder, his father told the paper.

“He won Airman of the Quarter five times and Airman of the Year once,” Mark said. “He proudly served in Guam, South Korea and in Kuwait.”

He also “was very athletic and enjoyed adventure,” his father said, according to the Courant.

“I was very very surprised for the neighborhood. Because it’s a good neighborhood -- very very quiet,” neighbor Jorge Laviola told Hartford's Fox 61.
