“We still have another armed and dangerous man out on the streets,” DA Ferman told reporters this afternoon.  “We want people to know that we are looking for him, we want people to know not to approach him.  But that if he is seen or if someone knows where he is, they should contact law enforcement right away.”

Police did recover four assault rifles, but at least five guns were taken from the home sometime between May 29th and June 2nd.
