Henry Toeurn funeral expenses

I'm trying to raise money for my fiancee's brother that passed away this morning, December 26th, unexpectedly in Houston, Texas which didn't have any life insurance. He was 38 years young and was healthy. My fiancee, Jantha Toeurn, had just spoke with him Christmas night and he was just fine.  Jantha and his brothers, Terry, Buntha and Brian are the only ones left. Henry is preceded in death of their mother, Loeurn Ving (2007), from California and their father in 2018, which was from Houston, Texas.
