He had been hospitalized for some time due to brain cancer. His parents had been by his side throughout his struggle and his passing has left them devastated.

After his death, Grayson’s mother, Michelle Arroyo shares on Instagram, ‘I’m heart broken to share that my sweet Gray passed away Sunday night. It was very unexpected as last week he had CSF drawn from his shunts and they adjusted the valve setting of his shunt and he was doing much better. We were still struggling with his diarrhea and I was giving him potassium 3 times a day because it was dropping so low. His heart stopped here at home and I performed chest compressions to get it going until the paramedics arrived and took over. When he left for the hospital he looked good and was breathing on his own but his heart gave out again at the hospital. I don’t have all the answers now, but I do know that the last few months with fevers, infection, and low potassium most likely took a toll on my sweet boys heart. I’m still in shock and going through the motions of dealing with all the details. I know Gray is playing cards with Gramma and playing Trouble with our beloved Diane. His dog Mo is right at his side as he never left him’.
