Support Dustin Garner's funeral,hospital bill,kids

My younger brother shockingly passed away at 34 years of age by sudden cardiac arrest. He had a heart condition that we were unaware of until it was too late. Dustin has a 8 year old cancer survivor daughter named Bristal Garner and a 2 year old son named Dega Garner. His kids were his life! Our family would greatly appreciate any help with his funeral, hospital bills, as well as future support of his kids.
