Support Linda and Shawn after John Plunkett's Passing

I am David Plunkett; my brothers and I are trying to raise funds for my brother John Plunkett's family. He was the only caretaker for his wife Linda and son Shawn. John suffered with many heart attacks last year and congestive heart failure last September. After surviving all of them he was diagnosed with Stage 4 Bone Cancer all over his body just 2 weeks ago. Having the cancer advance so rapidly in a 1-week period that his prognosis was cut down to a few days, he only made it 2 more days. Both his wife Linda and son Shawn have MS and Diabetes among a list of other physical conditions. We were not prepared to deal with John leaving us so incredibly fast as he has been able to get through everything so far.
