Georgia environment boss, who testified about BioLab chemical explosion, collapses and dies moments after revealing what he knew | 9 Oct 2024 | A Georgia environment boss collapsed suddenly on Tuesday and later died in the hospital -- on the same day after testifying about the BioLab chemical explosion. Kenny Johnson, 62, was Rockdale's state representative supervisor for soil and water conservation. He testified about the BioLab chemical fire that spewed clouds of chlorine gas and smoke in Conyers, where Johnson lived with his family. He later collapsed near the state Capitol and was rushed to Grady Memorial Hospital where he died. During his recorded testimony, Johnson claimed this was the second time he had asked for a criminal investigation -- the first time was three weeks prior to Georgia Senator Jon Ossoff, whose office told the environment boss they'd do an injury by utilizing the Department of Justice.
