On 7 December 1972, construction workers uncovered human remains near Lehrter station in West Berlin just 12 m (39 ft) from the spot where Krumnow claimed he had buried them. Forensic examiners determined that the size of the skeleton and the shape of the skull were identical to Bormann's. Likewise, the second skeleton was deemed to be Stumpfegger's, since it was of similar height to his last known proportions. Composite photographs, where images of the skulls were overlaid on photographs of the men's faces, were completely congruent.
On December 18, 1972, a few weeks after the election, Biden's wife and one-year-old daughter Naomi were killed in an automobile accident while Christmas shopping in Hockessin, Delaware. Neilia Biden's station wagon was hit by a tractor-trailer truck as she pulled out from an intersection. Biden's sons Beau and Hunter survived the accident and were taken to the hospital in fair condition, Beau with a broken leg and other wounds, and Hunter with a minor skull fracture and other head injuries. Doctors soon said both would make full recoveries. Biden considered resigning to care for them, but was persuaded not to by Senate Majority Leader Mike Mansfield. In later years, Biden commented that the truck driver had been drinking alcohol before the collision, but these allegations have been denied by the driver's family and were never substantiated by the police.
