Tenant deceased, having problems with family members

[Misty James]

My longtime tenant passed away. The tenant got married after moving in, and never officially added spouse to lease.  I never had a problem with spouse, so agreed to allow spouse to stay on month to month basis. The problem is I am getting calls from deceased adult children. Apparently they never got along with spouse and are aware that spouse was never added to lease. They are asking me to allow entry into house to take possession of deceased belongings as "spouse never bought anything in the house" and "tenant didn't have will". I have directed them to contact police but they continue to call me. I am starting to become concerned about damage of property so I am trying to tread lightly and avoid involvement.

I have many questions but the big one is...Am I missing something (legally), should the deceased family be allowed into property because spouse was never added to lease?
