A mass shooting threat leads to a stash of weapons at a home in Maryland.

FOX News Radio’s Rich Johnson has details from Washington:

Police say it started earlier this week when a man who was about to be fired from his job made threatening calls to that business, calling himself ¬†‘A Joker’.

Prince George’s County Deputy Chief Henry Stawinski says that concern increased when police from another county talked to the man.

(Stawinski) “During a field interview with their officers, the individual was wearing a t-shirt that said ‘Guns don’t kill people, I do’.”

Authorities got an emergency order to hold the man for a mental evaluation, then found thousand rounds of ammunition and at least two firearms in his house.
