The next of kin of Charles Manson have until a week from Wednesday to claim the remains of the man who inspired a cult following to commit mass murder. If they do not, the taxpayers of California — who picked up the tab for Manson for the last 48 years of his life, all of which he spent in prison — will pay once again to have his body returned to dust, most likely by cremation. Manson, a small-time criminal who enlisted young followers to commit a string of killings in 1969 in Los Angeles, died of natural causes Sunday at age 83.
