Thanks guys. I got more details on what happened. Apparently he was home alone and decided to have a bath. The hot water triggered a massive seizure and he basically drowned in the tub with the water still running. Which overflowed and flooded the bathroom and garage below.
I went to visit with my cousin yesterday. It was sad. Her family is part native Canadian (my uncle was married to a native woman back in the 80s until she died in a car accident). So he and his wife (both white) have 3 native children.
Anyways, her son who passed away was diagnosed with both autism and epilepsy. Despite being told he would never complete high school and would be in a home when he was 18, he did graduate high school, had a part time job, and also was enrolled in college in a specialized business program. He was also involved in scouts with a different troop in the city. And participated in special Olympics.
When he enrolled in college, he even signed up for a life insurance policy they offered which is what will now pay for his funeral.
For those interested, here's the link to his obituary.
