The photo from the 2015 yearbook was from the Florida school. You can tell that because another student pictured there is wearing an “Eagles” sweatshirt (mascot of the Florida school).
The story saying he graduated in CA in 2015 is erroneous, and possible an intentional spoof, or distracting shill.
Thanks ... so much disinformation woven throughout this spextacle ... now who likes to do that??? Oh yeah! The Russians ... lol. BTW, the boy is such a leftist fool that faux issue caught me believing it!
