A chilling surveillance video showing the last minutes of Cst. Eric Czapnik's life was entered into evidence Wednesday as the trial of his accused killer continued.

The 11-minute long video shows Czapnik stumbling into the Civic campus of the Ottawa Hospital just minutes after he was stabbed in the parking lot. A large amount of blood can be seen on Czapnik's chest but he manages to walk into the building without assistance.

Seven minutes later, a handcuffed Kevin Gregson, the former Mountie accused of Czapnik's murder, is escorted into the building by police officers.
