Volunteers made quick work, erecting the playground in just three days. The playground was organized by a nonprofit foundation Where Angels Play, which has built 55 of these across the country in tribute to local heroes.

“It is, in fact, a tribute to an outstanding young man who has left an indelible mark on all of us here in Randolph,” said Randolph Councilman Ken Clifton.

Simmonds died in 2014 from injuries he suffered a year earlier when a bomb went off near him in Watertown during a police shootout with the Boston Marathon bombers. He was 28.
