A phone company official testifying in Aaron Hernandez's murder trial says several text messages the former NFL player exchanged with a co-defendant before the killing are missing from his phone.

Prosecutor Patrick Bomberg on Friday went through dozens of nondeleted text messages Hernandez exchanged with Ernest Wallace in the days surrounding the June 17, 2013, killing of Odin Lloyd.

Hours before the killing, Hernandez sent several texts pushing Wallace to come see him.

On June 11, Hernandez asks Wallace if he removed everything from a car, including a clip. The following day, he says he needs ``those keys'' and things are ``crazy.''

A few hours later, he tells Wallace he wanted to kill him.

A Sprint official testified several other text messages in records didn't appear on the phone.
