Aaron Hernandez, the former New England Patriots tight end who was found guilty of the murder of Odin Lloyd, is depicted by the sheriff in charge of the Bristol County jail as a master manipulator who treats jail like another place he’s more familiar with.

“He doesn’t really look at it as jail,” Thomas Hodgson told the Associated Press. “It’s more like training camp.”

Hernandez, 27, has spent 18 months in the facility and should soon be assigned to a prison after being sentenced to life in prison without parole. Hernandez is appealing, but faces trial soon on two other murders.

“‘I’ll miss you guys, but they [the jury] got it wrong,'” Hodgson said he told inmates. “He didn’t really have much of a change in his demeanor. He pretty much still had a swagger in his step.”

Hodgson describes a man who uses charm to try to get extra sandwiches and other advantages but also is sensitive to perceived slights. He did once get into a fight with another inmate and was once accused of threatening to kill a prison guard and his family according to Hodgson. Still, he thinks Hernandez will adapt to prison.

“He’ll probably do fine. He’ll be able to talk his way through everything,” Hodgson said. “If someone’s trying to outwardly and aggressively disrespect him, that could create a problem.”
