TROY, NY – An upstate New York court accepted a mine manager’s guilty plea today to manslaughter in the second degree, a Class C felony. Anthony Valente, a mine manager at a Grafton limestone quarry, admitted to causing Darren Miller’s death in October 2022 by recklessly disregarding and overriding safety features of a crane Valente was operating, which resulted in a piece of the crane striking Miller, a 35-year-old mechanic, and causing his death. The manager agreed to serve a six-month jail sentence and five years of probation.
