Authorities are trying to determine the cause of an accident earlier this week in Riverbank, California that claimed that claimed the life of a sanitation worker. News sources say 30-year-old Ismael Martinez-Huertas, a father of two, was crushed by a hydraulic mechanism on a garbage truck Monday afternoon.

A 24-year-old worker was killed at work last week when hundreds of pounds of plate glass fell on him, crushing him. News reports say Damarcus Laquan Calloway, an employee of Virginia Glass Products in Ridgeway, North Carolina, died April 22 from traumatic injuries.
