Joint Tenants issues

[Andy Liu]

Hello everyone , i got a issue that I want to see how you guys will handle it

. I rented one of the house to a 2 people, they are not family member but just friends. they signed the lease agreement together which if one person decided to quit or not paying rent for whatever reason, the other party will also be responsible for the whole amount of rent

Recently, one of the tenant got into a terrible car accident and will be at the hospital for at least 3+ months and currently not conscious. his family just contact me try to see if he can quit the lease. And the other tenants want to stay and willing to try to look for another housemates. 

I just wondering how would you guys handle this situation? thanks for any input :)
