03/10/21 WorkersCompensation.com Martinez, CA (WorkersCompensation.com) - Earlier this week, the Contra Costa County District Attorney's Office filed a felony complaint against Segundo Collazos, the owner of Amazon's Landscaping Company based out of Concord. The charges relate to the 2018 death of Manuel Peralta, then 68, of Antioch, California, who died while operating a rented tree stump grinder in San Ramon. At the time of the incident, defendant Segundo Collazos had a suspended license with the Contractors State License Board. The investigation began from the California Department of Industrial Relations' Division of Occupational Safety & Health Bureau of Investigations. The first felony alleges that defendant Collazos permitted the victim Manuel Peralta to use a stump grinder in a manner contrary to manufacturer recommendations and to work in the danger zone of the cutting wheel, resulting in his death. The second felony alleges that Collazos failed to properly train Peralta on the proper and safe use of the stump grinder, also resulting in his death.
