Casen Garcia, 22, a machine maintenance worker, died at the end of his shift at the Tyson Foods plant in Joslin, Ill., earlier this month and the cause of death is under investigation.

Although a preliminary autopsy report revealed that Garcia had an enlarged heart, the Rock Island County Sheriff's Department is investigating the situation, and the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) is also conducting an inspection.

Tyson Foods issued the following statement: "We're cooperating with authorities as they investigate the passing of one of our team members from our Joslin, Ill., facility. The team member experienced a medical episode on July 9. We extend our thoughts and prayers to the team member's family, friends, and co-workers."

Members of the victim's family have been speaking out about the conditions at the plant.

Garcia leaves behind a 14-month-old son.
