Julie Ann Tureson, 33, was found dead inside her minivan in a storage unit on East Platte Avenue in Colorado Springs on April 22, 2016. Her family had filed a missing person report that prompted the discovery. An investigation determined she had been shot to death and her death was ruled a homicide.

Investigators quickly focused on her 38-year-old ex-boyfriend, James Woo. The couple had a history of domestic violence calls and reportedly broke up about a week before her killing. Authorities believe the killing was premeditated and suspect Woo placed Julie’s body in the minivan and drove it to a storage unit he had rented two weeks earlier.

Law enforcement tracked Woo to Denver, where he boarded a flight to Seattle and was preparing to depart for Hong Kong when Homeland Security officers arrested him on the plane about an hour before departure. Woo, a San Francisco resident, was booked on a charge of first-degree murder. Police also found he used online dating apps and were seeking to speak with several women in the San Francisco and Denver areas who had communicated with him.
