Ardeth Mary Margaret Wood (October 28, 1975 – August 6, 2003) was a Canadian graduate student who was killed in a forcible drowning in Ottawa.
Wood spent most of her life in Ottawa, where she graduated from Lester B. Pearson Catholic High School in 1994 and studied philosophy and history at Carleton University.
She was last seen on August 6 riding her bicycle on a path along the Sir George Ettiene Parkway in the city's east end.
News of her disappearance was reported widely in Canada, and the entire city of Ottawa rallied around a search effort that involved the police, the military and hundreds of volunteers.
Randy Wisker led the investigation into Wood's murder, and relied on a loose collection of tips prior to the arrest.
