The triple murder at a Pizzeria Uno on Super Bowl Sunday all came down to a matter of street honor, according to the killer's friends.

Tron S. Johnson, 22, was sentenced to 100 years in prison Friday for the murders of Curtis Poston, Terrance Sneed and Charles Harrison at the Largo restaurant on February 3, 2008, after an escalating argument over the football game.

Security cameras captured patrons fleeing the restaurant after the violence began and the first two men were killed. You can see the soon-to-be third victim run away from the restaurant. Johnson pursued the fleeing man, killing him in the parking lot.

In the courtroom, Johnson called it a case of self-defense. His mother said the same outside the courthouse Friday.

"All I want to say is my son would never do nothing like that, unless somone did something to him," said Mrs. Johnson, who didn't want to be identified.

By all accounts, Johnson was provoked by the victims. They were all watching the Giants-Patriots Super Bowl. Curtis Poston was particularly agressive, loud and threatening toward the smaller Johnson, said witnesses. Johnson, claiming he feared for his life, called someone who delivered Johnson's gun to the scene. You can see Johnson leave the restaurant to get his gun on the surveillance video.

One of Johnson's friends said that in their world, Johnson had to defend his honor.

"He came to the restaurant to have a good time -- he ain't start nothing. Guys came in and started stuff with him -- It was self-defense," said Johnson's friend, Jeremiah Sweeney.

Sweeney and some of Johnson's other friends confronted State's Attorney Glenn Ivey in front of reporters outside of the courthouse. They could not believe what happened was not considered self-defense.

Ivey strongly disagreed, saying Johnson had a clear choice.

"I feel that we've got to hold these young men accountable for these kinds of actions. This is a case where he walked outside to get a gun -- all he had to do was keep walking and those three people would still be alive. And he wouldn't be looking to spend the rest of his life in jail," said Ivey.
