A husband and wife from Texas will be held without bail for four months as authorities continue to investigate why they had an arsenal including an AK-47, an AR-15 with a grenade launcher, a large-capacity shotgun, a bump stock and numerous rounds of ammunition in their Tewksbury hotel room.

Francho S. Bradley, 59, and his common-law wife, Adrianne Jennings, 40, both of Frisco, Texas, were ordered held after a dangerousness hearing in Lowell District Court, six days after the weaponry was found in their room.

Bradley had told police that his reasons for possessing the firearms were “classified,” that he was waiting to be “deployed” and that he was “in this area working for a government agency that is dealing with a virus,” raising concerns about his mental health, Assistant District Attorney Daniel Harren said.

“He has this perception of himself and who he is,” Harren said. “He talked about having a scrambled radio on his counter in case he got a call from a government agency to execute a mission. He tried to walk that back a little bit. I really don’t see someone in their right mind, saying to a number of police officers, ‘I’m waiting for my call from the government.’ He seems to have this idea of himself that he’s waiting for his mission, for the apocalypse, some kind of civil unrest.”

However Bradley’s lawyer, Robert Normandin, said not only is his client sane, he is a running a business and trying to win defense department contracts.

“Mr. Bradley is not a danger to anyone,” he said. “These are weapons he’s accumulated over the years. He’s bought legally. He owns legally, in Texas. He is licensed to carry. He has a lot of former military experience. It’s not unusual for someone to have a collection of weapons. He is nothing other than an entrepreneur who is trying to start a business to do something. There is absolutely no nefarious purpose for him having any of this stuff. I’ve seen no evidence in the hours and hours of conversations that I’ve had with him that there are any mental health issues.”

While the guns were purchased legally and Bradley had a license to carry in Texas, those credentials are not recognized by Massachusetts, making possession a crime in this state.

Bradley and Jennings are due back in court April 26 for a probable cause hearing for possession of the weapons. They also are the first people in the country charged with possession of a bump stock under a law passed in Massachusetts in the wake of last year’s massacre in Las Vegas.
