MARQUETTE - A male Upper Peninsula juvenile has been identified by police as a suspect in a series of bomb threats made Friday in areas throughout Marquette and K.I. Sawyer.
Because the suspect is a juvenile, the Marquette County Sheriff's Office is not releasing his name.
Police said while investigating a bomb threat made against Sawyer International Airport, another threat was called in to the Sawyer Medical Center. After the second call, police said they discovered the identity of the suspect, who was then taken into custody and transported to Marquette General Health System for psychiatric treatment.
Police said the suspect remains at Marquette General and that no charges are pending as the case is still in the investigation phase.
Officials found two suspicious packages Friday while searching the Sawyer airport and medical center after the threats were made. Police said the package found inside the medical center was found to contain parts assembled to replicate an explosive device.
Members of the Michigan State Police bomb squad out of Gaylord disrupted the device using a robot with a .50-caliber water charge, which blew up the package and saturated its contents with water.
A bomb-detecting canine also alerted on a backpack in the airport, which was later found to contain camping gear. Police said they do not believe the backpack is linked to the bomb threats.
All inbound flights to Sawyer International were canceled Friday, though normal airport operations resumed Saturday morning.
Threats were also made against North Star Public School Academy, Marquette General Hospital and Northern Michigan University. Police said all five bomb threats are believed to be linked to the suspect.
The threat against North Star caused a complete evacuation of the school, located on Wright Street in Marquette. A search of the building found nothing suspicious and classes resumed as normal Monday.
Police also cleared MGH and NMU Friday, having found nothing suspicious.
An investigation into the threats and the device found at the medical center is ongoing.
