My sister`s funeral expenses

My sister Sheila was tragically murdered over the holidays. She went missing on Christmas and they found her body a few days later. She was suddenly taken away from her family in such a cruel senseless way
           She was a mother, a grandma, a great grandma, aunt, and a sister. She was loved very much and will be deeply missed. She was loved by many.
           I am trying to raise money for her children to help with the funeral costs and burial costs as this happened so unexpectedly and the costs are such a burden. Any amount would be greatly appreciated.
