Hate to say it but he was a nut that wanted to punish his wife, he was going to kill them regardless of what weapon was available. If he did not have a .38 special or Tec-9 he would have used something else. But hey they did a great job sensationalizing the story to push the "Agenda". Hell the way the story reads the TEC 9 was not even used in the crime, they found it in a bag which they go out of the way to mention it was a "banned" weapon. Talk about exploiting dead people to push the "Agenda".
"A Florida man armed with an weapon that had once been banned under federal law forced his wife to watch as he strangled one of his sons and then shot a second before turning a gun on himself."
"The Palm Beach Post reported on Sunday that Isidro Zavala had killed himself with .38-caliber pistol, but police also recovered a bag with a TEC-9 semi-automatic handgun, extra ammunition, duct tape and cutting shears from the crime scene."
But yeah that is a messed up story regardless of the bullshit antigun tone.
