WINNETKA, Ill. (STMW) – A “false alarm” sent a SWAT team to North Shore school Monday evening after the wife of a school employee called police thinking her husband was being held hostage by a man with a gun.
The woman called 911 about 5 p.m. to report a possible hostage situation at Carlton Washburne School at 515 Hibbard St. in Winnetka, a release from Winnetka police said.
The woman said she was listening to a cell phone call from her husband — an administrative employee of the Winnetka School District 36. She said she could not get her husband to respond, but could overhear the muffled sound of his voice, the release said.
Based on what she was hearing, she believed he was being hostage by a man with a gun in his office.
About 30 police personnel responded and set up a security perimeter. A search of the building indicated it was a false alarm and Lake County authorities verified the husband had arrived home safely, the release said.
Further police investigation found the district employee’s cell phone had inadvertently called his wife’s phone without him knowing as he drove home from work. The man was talking out loud and was misunderstood by his wife, who reported hearing only some of his words.
