He is in-charge of the Investigation of Sandra Harmon death by San Mateo County Sheriff Deputy John Baba and Deputy David Dominguez on May 5, 2020 just off of Main Street Half Moon Bay.
He was also the in-charge of the Yanira Serrano-Garcia death by Deputy Investigation June 3, 2014 also Half Moon Bay.
He was also SMCDA Inspector Jamie Draper’s Supervisor and he approved this Conclusion Summary of the Coroner’s Report in the Chinedu Okobi Death by Six San Mateo County Sheriff Employees on October 3, 2018.
Both Inspectors of San Mateo County District Attorney’s Office thought that Omitting the word Homicide and a deliberately misleading statement was fine.
That is why I have No Confidence in either one of them. I also think it is a criminal act to provide a false report in what should have been a Homicide Investigation.
San Mateo County should release the MAV videos and audio recordings of the death of Sandra Harmon, they should have done it the first day.
