Kelvin “Chuck” Mattocks was at a doctor’s appointment in downtown Boston one October Friday when his boss called. Mattocks was supposed to be off, but his supervisor at the drain company said he needed him to finish a job in the city.
Mattocks, 53, agreed to forfeit his day off, and by lunchtime, he and co-worker Robert “Robby” Higgins, 47, were working in a 12-foot-deep trench in front of a townhouse in an upscale neighborhood in the city’s South End. They were installing a sewer line when, suddenly, the walls of the trench collapsed.
“I’m looking down, and the guys are down there working,” carpenter Ken Bruneau said in an interview with NPR.
Bruneau was working inside the house and stepped outside for a cigarette break when he saw the trench give way.
“And next thing you know, I seen part of the trench engulf them from the waist down. Real quick. Like, whoosh!’’ he said.
