Walmart attack left man with 1 kidney in critical condition.

I'm trying to help the sweetest older couple get help paying for medical bills as they were attacked at Walmart by a random man . ms . Sam and Mr George are two of the kindest people I ever met and now he is fighting for his life .He already just got out of the hospital for kidney failure and was left with just 1 kindey . after being rushed to the hospital after the random attack his other kidney is beyond repair and he is in critical condition as they try to find him a new kidney . These people did not deserve this . His wife Sam was also nadlt injured after being hit in the fave multiple times trying to protect her husband. The video of the incident shows that not one person tried to help them . my heart is broken for this couple . please help me help them through this . we are hoping he even makes it out of this .
