Well, she left her two children behind.  If she did have insurance, I'm sure her kids could really use the money.  A lot of people that young don't bother to get insurance, though.  So I think that is sort of doubtful.

Children can also collect social security benefits up to age 19 if a parent dies, and has paid into Social Security.   But that assumes that she has worked.

She did disappear 8 months ago.   That would be a long time to be in denial.
