ICE Arrests Canadian Murder Suspect in Mississippi for Illegal U.S. Entry and Firearm Possession

The Department of Homeland Security says U.S. Immigration and Customs Enforcement agents arrested 28-year-old Canadian national Adrian Vincent Walker on March 23 at a residence in Tupelo, Mississippi, after he allegedly entered the country illegally while hiding under an alias. Walker was on Toronto police’s top-25 international "Most Wanted" list, accused of first-degree murder and attempted murder in a May 7, 2024 shooting in the city’s York District that killed 31-year-old Trevor Dalton John and wounded a woman. Acting DHS Assistant Secretary Lauren Bis credited ICE officers with getting "one of Canada’s most wanted criminals" behind bars and said Walker now faces U.S. federal charges for illegal entry and illegal possession of a firearm before extradition proceedings to face the Canadian homicide case. Canadian authorities say Walker previously served more than three years in prison there for aggravated assault, underscoring that he arrived in the U.S. with a serious violent record. The case highlights ongoing debates over how often foreign fugitives cross the southern border undetected and the role of ICE’s fugitive operations in tracking them once they are inside the country.
