WAUSAU, Wis. – Two 15-year-old boys playing an Internet card game threatened violence at their high school and showed a gun that appeared to be real, a prosecutor said. Card players in Boston alerted authorities, who canceled classes at the school Monday.

The boys appeared Monday in Marathon County Juvenile Court. Each was accused of one count of making a bomb threat and one count of using a computer message to threaten harm or injury, Assistant District Attorney Theresa Merriwether said.

School officials said classes at Wausau West High School would resume Tuesday as no bombs or weapons were found in the school.

The boys were placed in juvenile detention Sunday at 8:20 p.m., Marathon County Chief Deputy Scott Parks said.

Merriwether said a judge ordered them to remain in detention Monday pending further hearings.

She said a petition seeking to have the boys found delinquent for the crimes gave the following account:

The teens, who live outside Wausau, were playing an interactive game of Uno on the Internet Saturday when they used a live Web camera to make verbal threats of violence at the high school. They said they would use bombs and weapons.

The boys displayed a gun that looked real and demonstrated sparks from a battery as evidence of the plot. They claimed they would shoot people at a school assembly.

"They were asked if they were making bombs and they said they were," Merriwether said.

Three players who live near Boston took the threats seriously and alerted police there, who contacted the FBI and then Wausau police.

Parks said the search of the school found no bombs or weapons, but other evidence was collected.

Teachers returned to school Monday afternoon, and a boys' basketball game was being played as scheduled.

In juvenile court, punishments can range from supervision to being sent to Lincoln Hills School, a secure correctional facility, Merriwether said.

The boys told investigators that the gun they showed over the Internet during the card game wasn't real, she said.
