Is he in the Broward lists of MSD students?
I would think they keep the current list of students private since they are minors. The link I found for David Hoggs and the official Redondo Union high school website, is a part for the alumni and it looks like it is voluntary to sign up for it since they would be adults now.
Even though there is an added s to his last name, we know he lived in that particular city and the other TV news video shows he was there at the time. It would also mean he volunteered to be on that list.
