Five teenagers charged in juvenile court with making threats to commit shootings on the last day of school at Hutchinson High School will remain in custody.

After a Reno County judge ruled Friday that a 16-year-old boy would not be released from the juvenile detention center where he and four friends had been held since being arrested on Wednesday, the other four waived their hearings and will remain in custody.

The five face felony charges of solicitation to commit first-degree murder and criminal threat. They are all ages 16 and 17. They were arrested after the school reported the threats posted on Facebook. Court records indicate the threats were not aimed at specific people.

The Wichita Eagle reports the boys have all said the threats were a joke.
