A bodybuilder went on a killing rampage in Bosnia, fatally shooting 3 people, including his ex-wife ... even worse, he live streamed the entire violent escapade.
Nermin Sulejmanovic had his phone camera turned on as he streamed 3 separate videos to Instagram, capturing his demented murder spree Friday in the northeastern Bosnian city of Gradacac.
In his first video, Sulejmanovic boasted he was about to carry out a live execution before showing his badly beaten former wife on a porch.
