Grassi was heading to another call when he heard an MIT officer was down. When he arrived, Collier was on the ground, bleeding profusely and getting CPR. Grassi was first told Collier's gun was gone and there was an active shooter.

The prosecution introduced these photos of the crime scene on MIT's campus as exhibits yesterday.

Cambridge PD Anthony Grassi is testifying about shell casings he located behind Collier's cruiser.

by Sarah Stolper via Hearst Television 3/12/2015 1:43:11 PM
Once Grassi learned that info was incorrect, he worked on evidence gathering. He found 3 casings and marked them

by Kelley Tuthill via Hearst Television 3/12/2015 1:48:54 PM
Dr Renee Robinson from Medical Examiners office is the next witness.

by Kelley Tuthill via Hearst Television 3/12/2015 1:50:10 PM
Prosecutor stops to be sure courtroom monitors are off bc witness will present Colliers autopsy photos. Jurors will see paper copies. Observers will not see the images in courtroom 9. Media can view later.

by Kelley Tuthill via Hearst Television 3/12/2015 1:51:52 PM
Robinson has performed 1000 autopsies.

by Kelley Tuthill via Hearst Television 3/12/2015 1:53:38 PM
Robinson is graphically describing how an autopsy is done

by Kelley Tuthill via Hearst Television 3/12/2015 1:55:30 PM
Robinson is now explaining what happens when a gun is fired and a person is shot

by Kelley Tuthill via Hearst Television 3/12/2015 1:58:31 PM
A contact gunshot wound will create a muzzle stamp. A pattern around the hole of the entrance wound.

by Kelley Tuthill via Hearst Television 3/12/2015 1:59:07 PM
Gases and gunpowder will come out of the gun, not just the bullet, Robinson explains

by Kelley Tuthill via Hearst Television 3/12/2015 1:59:23 PM
Robinson performed Collier's autopsy.

by Kelley Tuthill via Hearst Television 3/12/2015 2:00:23 PM
She determined the cause of death was gunshot wound to the head caused by homicide

by Kelley Tuthill via Hearst Television 3/12/2015 2:02:03 PM
Bullets went into his brain and destroyed vital parts of the brain you cannot live with. 3 shots to the head. right hand two shots and a graze, Robinson said

by Kelley Tuthill via Hearst Television 3/12/2015 2:02:33 PM
Doesn't know which wound happened first, Robinson said

by Kelley Tuthill via Hearst Television 3/12/2015 2:02:43 PM
Intermediate range, penetrating wound. Gun not up against the skin, but wasn't far away, Robinson said.

by Kelley Tuthill via Hearst Television 3/12/2015 2:03:24 PM
Collier was shot between the eyes, closer to the left eye, Robinson testifies.

by Kelley Tuthill via Hearst Television 3/12/2015 2:03:44 PM
Robinson believes the gun was a foot or so away from Collier's head

by Kelley Tuthill via Hearst Television 3/12/2015 2:04:36 PM
Exhibit 728 is first. it's a photo of Collier's face at his autopsy. The jury will see now. we will not

by Kelley Tuthill via Hearst Television 3/12/2015 2:05:40 PM
Several jurors bring their hands to their face in what I can only imagine is horror at the photo before them.

Robinson continues to explain the devastating effect this bullet had on Collier. It severed his carotid artery.

by Kelley Tuthill via Hearst Television 3/12/2015 2:09:37 PM
Robinson now looking at exhibit 733. it's a bullet pulled from Collier's neck. We cannot see the photo, jury can.

by Kelley Tuthill via Hearst Television 3/12/2015 2:10:41 PM
The jury saw a surveillance video yesterday showing MIT Police Officer Sean Collier's cruiser parked to the left of the Koch Institute building on April 18, 2013. The prosecution drew a yellow circle around it.

The video also shows two people approaching the cruiser from the rear --- and walking up to the driver's side window.

MIT grad student Nate Harman testified yesterday that when he rode his bike past Collier's cruiser, he saw a young man leaning into the driver's window.

Harman said he made contact with the man who "looked startled" to see him, but figured he was an MIT student and didn't think anything more of it. Harman said he rode away.

Robinson says when bullets entered the body, they fractured apart.

by Kelley Tuthill via Hearst Television 3/12/2015 2:13:13 PM
The second gunshot wound was a contact wound meaning the muzzle was up against the skin. the bullet penetrated in but did not leave the body.

by Kelley Tuthill via Hearst Television 3/12/2015 2:13:53 PM
Robinson now talking about exhibit 729 another graphic image from the autopsy.

by Kelley Tuthill via Hearst Television 3/12/2015 2:14:53 PM
I cannot see the image, but it sounds gruesome as Robinson describes the discoloration of Collier's skin around the wound. The bullet enters the left side of Collier's cheek, up through base of skull, enters right hemisphere of the brain and comes to rest in another part of the brain. Robinson says the bullet is destroying portions of the brain that it goes through. important structures.

by Kelley Tuthill via Hearst Television 3/12/2015 2:18:12 PM
Here's another screenshot from the surveillance video that the jury viewed yesterday.

The prosecution says the Tsarnaev brothers approached the vehicle, shot Officer Collier multiple times at close range, tried unsuccessfully to steal his gun, and then left the scene on foot.

by Sarah Stolper via Hearst Television 3/12/2015 2:18:22 PM
"you can't function," Robinson testifies

by Kelley Tuthill via Hearst Television 3/12/2015 2:18:34 PM
Exhibit 737 is next. this is bullet recovered from Collier's brain

by Kelley Tuthill via Hearst Television 3/12/2015 2:19:22 PM
Prosecutor now focuses on 3rd wound to the head. another close contact penetrating wound, he says. In front of the left ear.

by Kelley Tuthill via Hearst Television 3/12/2015 2:21:42 PM
Left ear significant for prosecutors because bike riding MIT student Nate Harman testified he saw Dzhokhar Tsarneav at the drivers side door of the cruiser.

by Kelley Tuthill via Hearst Television 3/12/2015 2:22:46 PM
