How Can I Find Out If An Online Friend Has Passed?

hi. idk if this is the right sub for this. i'm an american [east coast] and i had a friend [19 yrs old and lived with his parents] from canada [east coast] who i met on instagram. recently, he had been going through a really hard time and had attempted to take his life multiple times. he used to watch my instagram story every day, almost right after i posted it, and he hasnt in over a week. i also messaged him about a week ago and haven't heard back at all. there is a possibility that he is in the hospital or a mental health facility also. is there any way i can check to see if he's okay? i don't have his legal name or last name. sorry again if this isn't the sub for this question.
