Beaten by guards until memory is lost in Texas

On Sept. 27, 2016 an inmate here at Wallace Unit (TDCJ) was smoking fake weed(K2) he supposedly got aggressive and beat up his celly. After which officers became alerted of the problem. Supposedly they sprayed him with three cans of gas after which they claimed he kept coming forward (in my opinion unlikely). So they tackle him to the ground with great force (multiple officers involved) and it doesn’t stop there they continue to beat him while he is in handcuffs with metal sticks until he is K.O…. After this he is taken to the ER where he dies of a heart attack and is revived. Later he comes back to the unit barely recognizable and on top of that with little to no memory of his life, he asked for his mom who has been dead for 2yrs. They shipped him off the unit.
