Rosario 'Chayo' Martinez-Lopez died while working on a condimium project at a Granby construction site when the unsecured trench he was working in collapsed and buried him. According to OSHA, Martinez-Lopez was working on his knees approximately eight feet deep inside a trench, tying in copper piping to a main water line. He suffered major head trauma and later died due to excessive blood loss. According to news accounts, another worker had stepped away for a few minutes. When he returned, he found the trench had collapsed, burying Martinez-Lopez. He then called 911. A joint news release issued by the Grandby Police Department and the 14th Judicial District Attorney's Office noted that the investigation was conducted by the police department and OSHA. Evidence from the two independent investigations was submitted to the District Attorney's office, which charged the defendant.
