The video was shown at the trial of Boston bomber Dzhokhar Tsarnaev. A redacted version that didn’t show the shooting was released to media on Wednesday.
A new video showing the ambush of the MIT police officer who was gunned down after the Boston Marathon bombing was released on Wednesday.
In the video, two people appear to approach Officer Sean Collier's parked police cruiser, then run away.
The video was shown in court at the trial of Boston bomber Dzhokhar Tsarnaev.
Out of respect for Collier's family, the court redacted the clip before releasing it.
MIT's Police Chief John DiFava testified in court Wednesday that he saw Collier earlier in the night on April 18, 2013, the day he was killed.
"I told him to be safe and I left," DiFava told the jury.
An MIT police sergeant who responded to the shooting told the jury about the gruesome scene.
"There was blood everywhere," Sgt. Clarence Henniger testified. "All over the car, his body, it was very difficult to try to get a grip on him and remove him."
Along with being accused of killing three and injuring more than 260 other people with a weapon of mass destruction during the 2013 Boston Marathon, defendant Dzhokhar Tsarnaev is charged with the murder of Collier.
Testimony related to the shooting death of Collier is expected to continue this week in the trial.
