Wallet access

I commented on a diff post and thought about trying a few years ago but long story , few hundred Bitcoin in a wallet somewhere my friend had before killing himself...if even possible and with permission from family is there anyway to recover that ? We used it for XYZ 2011-2012 ish and he dieded 2015 so pre cloud ? Computer is in landfill somewhere and family moved so ip wouldn't match although we were using an account to transfer to in France so idk just curious...will legit give half to family and half of the rest to anyone that could help...or is it just gone forever...easily 7500000-20000000 just out there or gone forever...maybe this is the new treasure hunts...sick just thinking about it
