Prosecutors Use Missing Texts From Aaron Hernandez's Phone As Evidence

There have been a number of testimonies, including one from Hernandez's fiancé Shayanna Jenkins, that could possibly tie Hernandez to the crime.

Prosecutors are eager to prove that Jenkins disposed of the bag after receiving a coded text message from her fiancé.

The house cleaner, Carla Barbosa, took the stand last week and was in tears after she saw the footage. She told the court that Jenkins was gone for a while and we she came back she appeared to be normal.

Later, Barbosa said that Jenkins took a phone call and she was seen looking out the window.

"She was crying. She was nervous, and she was walking back-and-forth," Barbosa said through a Portuguese translator.

The murder weapon has yet to be found, and it is believed that Jenkins helped in the disposal of the weapon.

Officials have found six shell casings that all came from the .45 caliber Glock that investigators says was the murder weapon.

Jenkins told the court that she doesn't remember where she disposed the big bag, but prosecutors are hoping to use her testimony to prove that Hernandez was involved in the murder of the semi- professional football player.

Hernandez has pleaded not guilty to the murder charges, and he currently remains in jail without bail.
