Support for a Family in Grief: Help Needed

Hey everyone, I’m making this because we’re trying to raise money for my older sister Santasia Coley. My sister is 27 years old with a 1 year old daughter. ON Tuesday august 13th my mother received a call from the emergency room stating that my sister was found unresponsive. We did not know the cause of it, immediately we rush to the hospital. When we arrived at riverside regional in Newport News they was already taken her to ICU. We requested that they give her a Ct Scan that would would give us some type of answers as to what happened to my sister but no answers. My mother then asked then to give her an MRI TOXICOLOGY TEST they didn’t do that, my mother asked that they call thee poisonous control center to see what type of test they could run on her to get some answers they wouldn't do any of that. They denied every single request that was asked of them. My mother did not sign any DNR forms to give them consent to make their own decision so they was supposed to give her the best possible treatments they could upon my mother’s request. Wednesday August 14th, my mother stayed over night with my sister. I arrived back at the hospital by 7am the doctors was still preforming blood work on my sister, and my family also arrived. My mom stepped out the room to go clean herself and my niece up because they have been there all night. The nurse came to me around 3 letting me know they will be preforming a brain dead test on her. I let my mother know and she denied that she wanted that test done. I then relayed the message. My mother returned and also stated that she didn’t want the test done and the doctor that was supposed to be taken care of my sister , stated that he was doing it anyways. When the results returned they then announced her deceased. My family is a strong believer of the lord and always believe that god has the LAST SAY SO. We continue to pray over my sister body and trust in god. Thursdays morning I’ve arrived back at the hospital at 8am as I was checking in I’ve received a message from my mom stating they were trying to take my sister off of life support. I walked into the room talked with my sister and prayed again. One of the nurse that was “taken care” of my sister walked in and I kindly and nicely asked her to please not mention that again because we want to give my sister body time to fight. She said ok then walked out. My brothers, Mother , niece , and I was all standing around talking with my sister when we saw Newport News and Hampton PD gather around the security office not thinking they were coming in for us. 15 minutes goes by and the PD and riverside security walked into the room stating that they was taken my sister off of life support weather we agreed or no. I then ask them again not to touch my sister as my mom was letting them know that’s not what she requested. My mother also requested that my sister be removed to a hospital on the other side of the water and the doctor denied it. Security then to move my chair aside and told us that we had to be removed from the room or we will be detained for trust passing. My 1 year old niece was standing in the room with her mother the whole time all of this was going on. They did not give her or us a chance to see my sister take her last breath. I feel that we was treated unfairly and if my sister was somewhere else she will still be here with us. What ever you could share is very and truly appreciated. Also till this day. We do not know the cause of my sister death. All funds will be going towards the funeral expenses and whatever is left will go into a trust fund for her daughter.
