The prosecution's interactive map is pretty cool. It has a diagram of Boylston street. Color dots indicate what was found where. When the prosecutor clicks on the dot, the jury can see a photograph of the evidence on scene. And now they are seeing the evidence in person

by Kelley Tuthill via Hearst Television 3/11/2015 1:24:37 PM
The FBI also previously released the above photo, alleging it showed part of a pressure-cooker bomb.

The jury is looking at a similar piece of twisted metal right now.

FBI Special Agent Chad Fitzgerald is describing his analysis of cell phone records during the week of the Boston Marathon bombings in April 2013 as well as a shorter period of time during Christmas 2012.

Prosecutors allege that Dzokhar called his brother Tamerlan in order to coordinate the explosions at the two locations.

The photo above showing the defendant on the phone in front of the Forum restaurant was introduced earlier as a government exhibit.

by Sarah Stolper 3/11/2015 2:29:13 PM
Fitzgerald says same tower was used as records show Dzhohkar called Tamerlan at 2:48 pm on Marathon Day.

Fitzgerald says he also examined phone records for a pre paid phone purchased 4/14 and used until 4/19

by Kelley Tuthill via Hearst Television 3/11/2015 2:31:26 PM
2:51 pm on 4/15 Tamerlan calls Dzhokhar, according to FBI agent who reviewed records

by Kelley Tuthill via Hearst Television 3/11/2015 2:33:47 PM
Fitzgerald says a witness reported the people involved in the bombing stopped at Whole Foods. The cell records helped investigators narrow the timeframe to examine store video.

by Kelley Tuthill via Hearst Television 3/11/2015 2:40:31 PM
Fitzgerald tracked the Tamerlan phone use later that evening from his home on Norfolk street in Cambridge

by Kelley Tuthill via Hearst Television 3/11/2015 2:41:36 PM
Fitzgerald now showing a map that depicts 4/16/2013. Tamerlan's phone being used in Boston area. Dzhokhar's phone is used there too in the morning, but later in the day use moves to the New Bedford/Dartmouth area.

by Kelley Tuthill via Hearst Television 3/11/2015 2:43:12 PM
Moving onto 4/17/13. Records show Tamerlan phone using Boston area towers. Dzhokhar's phone uses towers in New Bedford/Dartmouth area.

by Kelley Tuthill via Hearst Television 3/11/2015 2:44:48 PM

by Kelley Tuthill via Hearst Television 3/11/2015 2:47:04 PM
4/18/13 records show a call btwn Tamerlan and Dzhokhar phones. Tamerlan calls Dzhokhar phone 11 pm

by Kelley Tuthill via Hearst Television 3/11/2015 2:49:17 PM
FBI Special Agent Chad Fitzgerald says he was able to use cell phone records to help investigators locate images of Dzokhar Tsarnaev at the Whole Foods market on Prospect Street in Cambridge.

Fitzgerald testifies he told investigators to focus on store surveillance video shot from 3:15-3:30pm.

Investigators say that's when video shows Tsarnaev entering the supermarket and purchasing a half-gallon of milk.

by Sarah Stolper 3/11/2015 2:51:41 PM
That's the last call between the 2 phones, Fitzgerald testifies.

by Kelley Tuthill via Hearst Television 3/11/2015 2:52:25 PM

by Kelley Tuthill via Hearst Television 3/11/2015 2:57:30 PM
Defense attorney Miriam Conrad now cross examining FBI cellular expert

by Kelley Tuthill via Hearst Television 3/11/2015 3:34:39 PM
Conrad is asking about calls the two brothers made prior to the bombing

by Kelley Tuthill via Hearst Television 3/11/2015 3:36:11 PM
Conrad asking Fitzgerald how they can tell how long the call is

by Kelley Tuthill via Hearst Television 3/11/2015 3:40:48 PM
I do not know if the call was physically connected person to person, Fitzgerald testifies.

by Kelley Tuthill via Hearst Television 3/11/2015 3:41:48 PM
Fitzgerald says the length of call duration on T Mobile starts once you connect with the tower not necessarily the other person.

by Kelley Tuthill via Hearst Television 3/11/2015 3:42:45 PM
Conrad focused on the 249 pm call being 19 seconds and points out it includes connection time and ring. call from tamerlan to dzhokhar at 2:51 pm listed as 30 seconds. but that's not the length of the call if they did tallk? correct, Fitzgerald says

by Kelley Tuthill via Hearst Television 3/11/2015 3:47:53 PM
Conrad asking about 4/15/13 6:51 gmt which is 2:51 pm call. extraction shows 18 seconds long. .this expert is talking about cell technology not extracted data, prosecutor argues

by Kelley Tuthill via Hearst Television 3/11/2015 3:51:17 PM
Conrad says 249 pm call was 8 seconds long. Fitzgerald says he's not sure about that.

by Kelley Tuthill via Hearst Television 3/11/2015 3:52:33 PM
Conrad asking about records showing Dzhokhar's location in Cambridge 12/25&26 in 2012

by Kelley Tuthill via Hearst Television 3/11/2015 4:02:13 PM
Conrad asking in general if most of Dzhokhar's cell use was mostly in Dartmouth area. Fitzgerald says yes

by Kelley Tuthill via Hearst Television 3/11/2015 4:02:44 PM
Prosecutor back up asking about 2:49 pm call btwn Dzhokhar and Tamerlan. Fitzgerald says it was the first call of the day between them

by Kelley Tuthill via Hearst Television 3/11/2015 4:03:47 PM
Records show that 2:49 pm call lasted 19 seconds meaning that's how long the call used resources on T mobile network. not necessarily how long any potential call lasted

by Kelley Tuthill via Hearst Television 3/11/2015 4:04:51 PM
We are still listening to testimony about the FBI's analysis of cell phone records that show calls between the brothers, especially on Marathon Monday.

This photo shows Tsarnaev holding a phone to his ear in front of the Forum restaurant --- the site of the second explosion on Boylston Street.

You can see Jane and Michael Richard standing on the barricades on the left side of the photo.
