Suspect in mosque fire had made anti-Islamic Facebook posts
(AP) — About two months before Joseph Michael Schreiber allegedly tried to burn down a mosque sometimes attended by Orlando nightclub shooter Omar Mateen, he posted on Facebook that "All Islam is radical" and that all Muslims should be treated as terrorists and criminals.
Thompson told a news conference that Schreiber, who has a criminal record, was taken into custody on a street in Fort Pierce by authorities acting on tips from members of the community and aided by surveillance video taken from the mosque and elsewhere.
Thompson said a search warrant was executed at Schreiber's home, where investigators reported finding evidence linked to the arson, as well as anti-Islamic social media posts.
Mateen was killed by police after opening fire at the Pulse nightclub on June 12 in a rampage that left 49 victims dead and 53 wounded, making it the worst mass shooting in modern U.S. history.
A weekend surveillance video from the mosque showed a man on a motorcycle approaching the building with a bottle of liquid and some papers, then leaving when there was a flash and shaking his hand as though he may have burned it, Thompson said.
Sheriff's officials had released the video and asked for the public's help in identifying the arsonist.
