Sheriff investigating Oregon massacre posted Sandy Hook truther video on Facebook

Douglas County Sheriff John Hanlin -- who is overseeing the investigation of the mass shooting at an Oregon community college -- posted a video on his Facebook page that suggested the Sandy Hook shooting was a hoax, according to Mother Jones.

One month after the Connecticut shooting that claimed the lives of 26, 20 elementary school children and 6 adult staff members, Hamlin linked to the video called: "The Sandy Hook Shooting - Fully Exposed."

On his post he wrote, "This makes me wonder who we can trust anymore... Watch, listen, and keep an open mind."

Hanlin has already for opposing additional gun control laws following the Sandy Hook shooting in 2012, writing to Vice President Joe Biden: "Gun control is NOT the answer to preventing heinous crimes like school shootings. Any actions against, or in disregard to our U.S. Constitution and 2nd Amendment rights by the current administration would be irresponsible and an indisputable insult to the American people.”

Hanlin is charged with investigating the shooting at Oregon's Umpqua Community College that left 10 dead, including the shooter Chris Harper Mercer, and at least 10 injured.
