Please help us lay " china " to rest! My little big sister

Family and friends, I never thought I would have to do this for my little big sister!

Edith Iracema Gutierrez- Amarillas, aka "la china", has left us with a broken heart! Her unexpected passing is something we are still trying to understand. We have no answers as of yet on her cause of death. I ask if you have it in your heart to help us lay my little big sister to rest! Please share, that also helps a lot!

Thank you in advance.
