My sister was killed in an accident

My sister, my best friend, was tragically killed this morning on her way to work while riding her bike. She leaves behind 2 children, one of whom is non verbal autistic and has a mental age that of a toddler. As far as I know she did not have any type of life insurance and due to her son's disability, her husband has not been able to work (the son needs round the clock care), she was working full time for Amazon and was paying the household expenses. Any money received will be used for her funeral expenses and any other expenses that may come up.
