A vigil honoring the late Edward Passetto will take place at 6 p.m. on Monday at Park Square.
Participants are invited to bring signs with quotes from his letters or accurate statistics regarding his cause.
At dusk, the group will light candles, share memories and have a moment of silence and prayer for Passetto and his loved ones.
Passetto was a 28-year-old Marine Corps veteran who died May 11 in an apparent suicide on Monument Mountain in Great Barrington. He had struggled with post-traumatic stress disorder, anxiety and depression. A Lee native, he resided in Pittsfield.
