Students in Plattsmouth to return to school Thursday

Students will return to Plattsmouth Community Schools on Thursday after police investigated a social media threat about a shooting purportedly planned for Plattsmouth Middle School.

School was canceled Wednesday after a threat that was deemed credible by officials was posted on social media.

Superintendent Richard Hasty said the Plattsmouth Police Department and Cass County Sheriff’s Office have wrapped up their investigation.

“Law enforcement believes there is no longer a threat, and the student has been removed from school,” Hasty wrote in a letter sent to Plattsmouth parents.

The case is now in the hands of the Cass County Attorney’s Office, Hasty said.

Additional support and security will be in place Thursday when classes resume.

Hasty said the district appreciated the support from Plattsmouth police and the Sheriff’s Office “as we work cooperatively to ensure our campuses are safe for students and staff members.”

Meanwhile, there was added security at Omaha North High School on Wednesday after a series of text messages that police said appear to be a hoax threatened violence at the school.

The text messages are associated with an out-of-state email address or telephone number, North High Principal Gene Haynes wrote in an email sent Tuesday evening to staff and parents.

Several other school districts have received similar threats that appear to be connected to the hoax, Haynes wrote.

The added district security and police were planned “in an abundance of caution,” Haynes wrote.

Elsewhere, a Des Moines suburb called off classes Tuesday due to a threat to students and parents. School was to resume two hours late Wednesday in Johnston, Iowa.

Johnston Community School District officials said Wednesday’s two-hour delayed start means secondary students will start at 9:45 a.m. and elementary students will start at 10:35 a.m.

Classes will be dismissed at the normal time, not the Wednesday early-release time. Extra officers will be stationed at the schools.

The closure affected about 7,200 students and 1,000 employees.
