Here's the type of stun gun DCFS officials confiscated at the Jackson family home last night -- and according to the manufacturer, it's the smallest, most powerful single battery unit on the market.
Sources tell TMZ Jaafar Jackson ordered a Scorpion 300,000 volt stun gun online. According to the company website, "the power derived from only one 9 volt battery is unreal."
It also fits easily into a pocket or purse.
As TMZ first reported, DCFS officials just returned to the Jackson family home to further question the kids, family and employees on the property.
A family source tells TMZ, "Jaafar fired the gun into a piece of paper."
