CASSOPOLIS — Employees have been allowed back into the Cass County Law and Courts Building following an evacuation Friday.

According to the Cass County Sheriff’s Office, the building was evacuated after a bomb threat was called into 911 at 8:45 a.m.

The caller made mention of an individual who had been sentenced to prison through the court system and said court employees would “pay for that,” said Cass County Sheriff Richard Behnke.

Treating the threat as credible until fully investigated, the sheriff’s office conducted a search of the building using traditional methods and a bomb-sniffing dog. No bomb was found, and the building was reopened at 11:30 a.m. The sheriff’s office also searched the County Administration building, known as the Cass County historic courthouse. The building was reopened Friday afternoon.

Now, the sheriff’s department is following up on leads to find the person who called in the threat.

“We have technology and are working on tracing where the call came from,” Behnke said.  “We have officers in the field looking into leads now.”
