May 16—VERNON — The owner of a Manchester construction company and an equipment operator were expected to be sentenced Friday at state Superior Court in Vernon after pleading guilty to second-degree manslaughter last month in the 2022 death of a worker who was buried in a trench collapse.

Botticello Inc. owner Dennis Botticello, 69, of Suffield and Glen Locke, 67, of Somers each face up to five years in prison under their plea agreements, although their lawyers had the right to argue for lesser sentences, State's Attorney Matthew Gedansky said previously.

Their sentences likely also will include periods of probation, with the possibility of additional prison time if they violate release conditions, Gedansky said.

Both men originally were charged with first-degree manslaughter. They have been free on $50,000 bonds since their March 2023 arrests.

An investigation revealed that proper safeguards were not in place to prevent a collapse when the 8-foot-deep trench caved in and buried Dennis Slater, 56, of East Windsor on July 22, 2022, said Gedansky, who prosecuted the case.

Locke was the equipment operator working near Slater at the time of the collapse, Gedansky said.

Investigators with the federal Occupational Safety and Health Administration also found four serious violations in 2015 connected to Botticello Inc.'s trenching work at a Stafford worksite, Gedansky said.

OSHA previously fined Botticello Inc. $375,000 for the unsafe conditions it says contributed to the accident.

The deadly collapse happened the afternoon of July 22, 2022 at a new housing development. Slater, a Botticello Inc. employee, became trapped inside a trench when the dirt collapsed on him, Vernon police Lt. Robert Marra said at the time.

According to affidavits by Vernon police Detective Mike Patrizz, Locke, who was laying pipe into the trench with an excavator, told investigators the trench had collapsed twice that day before the collapse that killed Slater.

Locke also told investigators that workers typically used a "trench box" to hold the wall of the trench, but "the banks were holding up fine here. I guess we play the odds," the detective reported.

Patrizz wrote that he inspected the roughly 8-foot-deep trench after the collapse and "there were no indications that the sides of the trench had been sloped, benched or any other trench safety measures had been instituted in any place over the length of the entire exposed trench."

Locke told investigators that Slater tried to get out of the trench as it collapsed, and Locke could not stop the wall of the trench from collapsing with the excavator "because the pipe was still chained to it," according to the detective. Locke and two others jumped in and began trying to dig out Slater with their hands and a shovel but could not find him beneath the earth.

Locke said he then used the excavator to try to dig out Slater, and once they uncovered his hard hat, they began digging him out by hand, the detective reported.

Medics took Slater to Manchester Memorial Hospital where he was pronounced dead. The state Office of the Chief Medical Examiner later ruled the cause of death was "blunt impact injury of the head, torso and extremities with chest compression," according to the detective.

A friend of Slater's from Arizona sent police screenshots of text messages she had with him on July 12, 10 days before the fatal accident, in which he complained that he was working in a trench by himself and it had already collapsed twice, according to the detective.

Locke admitted during an interview that he knew the trench was supposed to have ladders every 25 feet, as required by regulation, according to the detective. But "the only ladders present in the trench when the police arrived after the collapse were the ladders placed by the fire department," Patrizz wrote.

At the Stafford job site in 2015, the Department of Labor reported there was no "competent person" inspecting the excavation for hazards and "no cave-in protection was in use."

During the previous inspection, officials interviewed Locke and found he was not a "trench/excavation competent person," the detective reported. When the Labor Department inspector brought that issue up to Botticello, the owner said Locke "knew enough" and it was "common sense stuff," the detective added.

The inspector told Botticello he needed to get his company trench and excavation competent person training, according to the detective, and Botticello "stated he would get Locke trained as a competent person immediately and he asked for several sources of training."

But when he was interviewed after the 2022 accident that killed Slater, Botticello indicated there had not been any trench competent person training, according to the detective.

He said he owned several trench boxes, but the detective said they were not on site at the time of the accident.

One worker told investigators after the collapse crews began cutting back the walls of the trench to a 45-degree angle for safety and went "beyond what was necessary" in case OSHA showed up at the job site, according to the detective.
