Mystery continues over death of ex Pentagon official
A Vietnam veteran who became a driving force behind the controversial memorial on the National Mall, Wheeler worked on nuclear, chemical and cyber issues at the Pentagon. He was the first chief executive officer of Mothers Against Drunk Driving, a secretary of the Securities and Exchange Commission, and a tireless advocate for veterans.
Police are retracing Wheeler's movements between Dec. 28, when he left his office outside Washington, and New Year's Eve, when his body was discovered in Newark. He was scheduled to take a Dec. 28 Amtrak train from Washington to Wilmington.
