The family of a Missouri man who died of mesothelioma cancer has been awarded $4.5 million in their asbestos lawsuit against three manufacturing companies. The mesothelioma lawsuit filed by the family of Robert Wagner alleged that he was exposed to asbestos during his more than three decade career installing asbestos-containing products.

According to the lawsuit filed against three manufacturers, Wagner worked for over 30 years installing tile, wood and other materials containing asbestos in buildings. For many of those years, construction sites containing asbestos were not regulated by the government regulators.

Following three weeks of testimony, the jury agreed with the family’s allegations that the three companies were responsible for the asbestos exposure that caused Wagner to develop mesothelioma. Jurors said that the companies knew that their products contained asbestos but failed to conduct studies of how much asbestos exposure would be deadly.
