The owner of a Vail, Colorado construction company facing felony manslaughter charges has surrendered to local law enforcement after the Summit County Sheriff’s Office in Breckenridge, Colorado, issued an arrest warrant on Jan. 24, 2023, related to the findings of a federal safety investigation into a deadly trench collapse in November 2021.
In May 2022, OSHA cited Peter Dillon, owner of the now-defunct A4S LLC, after a worker installing residential sewer pipes suffered fatal injuries when the trench around him caved in. The collapse resulted from deteriorating conditions at the project, which A4S LLC could have prevented by using legally required trench protection systems.
