A jury in Fall River, Massachusetts, found former New England Patriots player Aaron Hernandez guilty of all charges, including first-degree murder.

Hernandez, 25, was convicted in the June 2013 killing Odin Lloyd, a 27-year-old landscaper and amateur weekend football player who was dating the sister of Hernandez's fiancee.

The first-degree murder charge carries a mandatory sentence of life in prison without parole. Hernandez was also convicted of two weapons charges.

Fox News senior legal analyst Judge Andrew Napolitano said on "America's Newsroom" that it is rare that jurors will return a first-degree murder conviction when all the evidence is circumstantial.

"This is an unusual case. Quite frankly, I am a little surprised. I expected that there would be some sort of a compromise verdict," Judge Nap said.

He pointed out that the defense's closing argument was also unusual, as Hernandez's attorneys changed their story and conceded that he was present for the murder.

"Their theory was, 'He wasn't there, he had nothing to do with it, this is just a coincidence, this evidence,'" Judge Nap said. "In their closing argument they say, 'He was there, he knows who did it, he didn't pull the trigger, he didn't do it himself.' That type of a concession is very, very risky."

Judge Nap also said that Hernandez faces two more murder charges that he will likely be tried on as well.

Massachusetts is one of the few states that permits inquiry into the jury's deliberations, Judge Nap explained. So all his defense attorneys have to do is find one juror who says that they just went along with the guilty verdict, and they could have a possible appeal.

"Because of that possibility that this could be undone, they will try him for the other crimes as well."
