California state investigator Brian Baudendistel continued his testimony on 20 November in the hearing to determine whether UCLA chemistry professor Patrick Harran will stand trial on felony charges of occupational safety violations that resulted in the death of Sheri Sangji. From a detailed summary of his statements during his first day testifying (19 November) by Michael Torrice at Chemical & Engineering News, it appears that Baudendistel recounted information in the 95-page investigative report he prepared for the California Division of Occupational Safety and Health.

Also testifying on 20 November was chemical safety expert Neal Langerman. Sangji "absolutely did not have sufficient skill, knowledge or training to be handling tert-Butyllium," Langerman testified, according to the San Jose Mercury News. He added that the Harran lab lacked appropriate equipment and protective clothing.

Because of scheduling issues, cross examination will take place on 18 December, the Mercury News reports.
