(Pluralist) However, Austin and Geoghegan’s dream trip came to a tragic and gruesome end when they got to Tajikistan, a ​weak state with a known terrorist threat that shares a border with Afghanistan, where ISIS and other terrorist groups are ​highly active. They were riding their bikes through the country on July 29 when a car rammed them, ​​according to CBS News. Five men got out of the car and stabbed the couple to death along with two other cyclists, one from Switzerland and the other from the Netherlands.

Two days later, ISIS released a video showing the same men sitting in front of the group’s black flag. They looked at the camera and vowed to kill “disbelievers,” ​according to The New York Times.
