Help me find a childhood friends grave who passed away in 2009

Hello everyone. I'm not from the US but in 2008-2009 I was with my dad for his work in Houston Texas. Now I'm back and I want to visit a friends grave but I'm not sure where his grave is. I have very limited information about him. His name was Mustafa (maybe he spelled it differently) he was a Syrian Christian, he had leukemia, right before he passed he was trying to protect from another kid who was trying to fight me. In the process he sustained an injury that cost his foot to be amputated. Shortly after that he passed away in 2009. The school we went to: school at Saint George place in Houston Texas. I know this is a long shot, but I’d really appreciate any help finding out more, like where he was buried, or if there’s any memorial or obituary. This is something I’ve carried with me, and I just want to honor his memory.

Thank you for reading.
