LARGO, Md. (WUSA9) -- Fright Fest lived up to its name not because of how scary it was inside the Six Flags amusement Park in Largo, but because of what happened out in the parking lot.

Witnesses say fights broke out Saturday night after the amusement park closed.

Three teenagers were injured and there was a traffic nightmare outside Six Flags as police were arriving and parents frantically tried to reunite with their children.

As a result the park increased security Sunday night.

Katrina Walker was at the park to pick up her son, Caleb, who had been celebrating his 15th birthday. But that celebration she said, ended in chaos: "I heard one or two gunshots, maybe three gun shots. I heard it. They came, all the police cars."

Walker says kids ran out of the park saying there was also a stabbing, but police will not confirm that report.

UPPER MARLBORO, Md. (WUSA9) -- A 65-year-old Maryland man has been found guilty of murdering his wife in 1972, Prince George's County State's Attorney Angela Alsobrooks announced Thursday.

James Bonnett was convicted of murdering his wife Diana in 1972. However, "received a new trial after the decision in Unger v. Maryland found that all the defendants from the 1970s whose judge told the jury that the instructions on the law were 'advisory only' could have another opportunity at a post-conviction hearing, the Office of the Prince George's County State's attorney said.

"This is a tremendous victory," Alsobrooks said. "No matter how long it takes or how hard it may be, we will not rest until we bring people to justice. Mr. Bonnett is a man with a terrible institutional record and has no remorse for what he did. He deserves to be in prison."
