Peter Leboon was concerned because his brother, who he said began showing signs of mental instability three years ago, had a permit to carry a concealed weapon.
"The last time I tried to get him help, we searched the whole house, six or seven of us, we couldn't find the gun," Peter Leboon said. "I found the permit, though, and destroyed it. Whatever happened to that gun, who knows?"
Christina Wilson, 28, a neighbor, said FBI agents took Leboon away in shackles on Saturday.
That morning, Leboon was outside his house screaming at his neighbors. Philly.com
Remember that obviously mentally ill man who was recently arrested for threatening Eric Cantor online? The guy who’s apparently been posting similar threats against a range of public figures, including President Obama and the pope?
