Video of the moments leading up to the brutal killing of a 23-year-old Ukrainian refugee was released Friday. (Warning: The video is graphic.)

Iryna Zarutska, 23, was stabbed and killed around 10 p.m. Aug. 22 while riding on Charlotte, North Carolina, public transportation.

A chilling video released by Charlotte Area Transit System shows Zarutska walking onto the train and sitting down. A few minutes later, the man sitting behind her — identified by authorities as 34-year-old Decarlos Brown Jr. — gets out a knife and raises his arm toward her. In an affidavit, a detective who worked on the case wrote Brown struck her three times and “blood visibly drips on the floor” as he walks away from her.

Zarutska was pronounced dead at the scene, and Brown was taken to a nearby hospital with non-life-threatening injuries. A judge ordered him to be monitored for 60 days, according to CNN; he will be arrested when he’s released and charged with first-degree murder.

The Charlotte Area Transit System did not immediately respond to a request for comment.
