The plaintiffs are claiming that the loaded chamber indicator on the Beretta was inadequate since the boy didn't notice that it was indicating a loaded chamber. Of course, he didn't check it himself, and then he point the firearm at his friend, and pulls the trigger. That is apparently Beretta's fault. Actually, the moron's behavior was dumber than that. He removed a loaded magazine, inserted an unloaded magazine (don't know if it was the same one or not), then shot himself. So (1) the guy knew the gun was loaded when he picked it up, and (2) a "magazine-disconnect" safety couldn't have done any good, since the firearm had a magazine in it when it was fired.
HERE is a link to another story about this case. The plaintiffs, the Dix family, parents of the boy shot by Michael Soe, plan to try again with yet a third trial. I guess their lawyers think they can win after two tries, and get a payday.
