Boston Marathon Bombing survivor Adrianne Haslet -- who lost her leg in the terror attack -- is FURIOUS after an appeals court Friday overturned the bomber's death sentence.
Dzhokhar Tsarnaev had been sentenced to die for his role in the 2013 bombing which killed 3 people and injured more than 250 others, including Haslet.
Haslet -- a professional dancer at the time -- required emergency surgery and lost her left leg from the knee down.
Her comeback story has been nothing short of inspirational -- she trained up and completed the marathon on a prosthetic leg in 2016.
