My dad Darryl is in the ICU on life support. He went in for Aorta surgery and now is on life support and they took his colon out as well. Found out they cut the blood of too long and it killed dads colon. Also dad has been there for 30 days and they never put in a feeding tube. Now all his organs are failing ... My sister is going to take him off support tomorrow but I just want every doctor and nurse know we are asking for an autopsy to see if this was your fault. You left my dad with dead tissue inside and closed him up. Now I'm sure he is getting septic. I know you guys are responsible for all this stuff going on with my dad. When the autopsy comes back that you guys did something wrong and covered it up. There will be hell to pay!!!!!!
