Another way you could get his address is through the two phone numbers you have. I frequently do this with annoying repeat callers. I just put the number on google search and sometimes I get lucky to find a name and address. Usually just a spammer. But in your case if it isn't available that way, there are usally an abundant number of choices willing to give you the info for a small fee.
I agree and to be honest it’s not that local for me to go trawling the streets..Sadly the only people he is MIA from is most likely us, whatever happened i am sure his family or friends are aware.
I Google mapped the city and it is fairly large so even the likelihood of finding him randomly or a place he haunts is going to be hard.
Maybe Num needs to add a emergency contact to our profile that is private to only him or the admins lol
