Thomas A. (Tad) DiBiase is a native New Yorker, born in Elmira and raised in Westchester County. He received a B.A. in Politics from Wake Forest University in 1987 and a J.D. from Brooklyn Law School in 1991. Mr. DiBiase joined the Washington office of the Wall Street firm Shearman & Sterling where he practiced corporate litigation for nearly four years. After turning down a clerkship with a federal district court judge in Texas, Mr. DiBiase joined the United States Attorney’s Office for the District of Columbia in 1995. He began prosecuting homicides in 1998, and during his time there tried 20 homicide cases. Although he was a federal prosecutor, Mr. DiBiase spent most of his career in the far grittier world of D.C.’s Superior Court, one of the nation’s busy urban courthouses. Mr. DiBiase specialized in domestic violence and forensic homicide cases. His high profile homicide cases included including United States versus Harold Austin, the city’s second "no-body" murder case ever, and United States versus Sydney Smith, where the main piece of evidence against Smith, a Metro employee who murdered his wife, was a cigarette the defendant left behind at the scene. Other cases he successfully prosecuted include United States v. John Williamson, a murder-for-hire case, and United States v. James Stewart, an attempted murder case involving a man who fired an AK-47 rifle down a street filled with children.
At various times he served as the Deputy Chief of the Misdemeanor Section, Chief of the Third District Homicide/Major Crimes Section, Special Counsel to the U.S. Attorney for Professional Development and Training, and Deputy Chief of the Homicide Section. He is the nation’s leading expert on no-body homicide cases and has a website that tracks and discusses these cases at www.nobodymurdercases.com. He consults with police and prosecutors throughout the country on no-body murder cases and has formally consulted on over two dozen no-body murder cases. He has appeared on television numerous times and has been quoted widely in newspapers throughout the country.
