Yeah. To their "estate". It's mentioned that some of his assets that didn't have a beneficiary named landed there and I think they were to be split according to the will of the deceased.
I think beneficiary trumps everything. But we are talking about what you could do with the money if you were (undeserving) beneficiary. Giving it back to the dead person (precisely donating it to their estate) is the right thing to do although probably imperfect because donations are often taxed.
"He died at 59, single and childless, with no will and no guidance on who should inherit his assets."
