GREEN BAY, Wis. (AP) -- Brown County prosecutors plan to make at least one more plea bargain offer before the trial for three teens accused of plotting an attack on a Green Bay high school.

District Attorney John Zakowski says he plans to extend an offer to William Cornell, Shawn Sturtz and Bradley Netwal in the hopes of resolving the case before trial.

The teenagers were arrested in September and are charged with conspiracy to commit first-degree intentional homicide and conspiracy to commit criminal damage with explosives for their role in the alleged plot to attack East High School.

Jury selection is expected to begin next week and the trial is expected to last two weeks.
