Oshkosh North High School went into lockdown Thursday morning following concerns about a teenage boy with a possible firearm. The lockdown was lifted after the boy was found and taken to a medical facility.
In a news conference, the Oshkosh Police Chief says concerns first arose the previous day, when the mother of a 16-year-old boy reported to a school social worker that her son was behaving erratically. Police say the mother told the social worker that her son had fired an AR-15-style rifle on their property.
After speaking with the school resource officer, the parent was advised to report the behavior to the Winnebago County Sheriff's Office. On Thursday, the school saw the boy arrive on the school property. Police say the school contacted the mother to ask if she had reported his behavior to the Sheriff's Office - she indicated that she had not.
Police say the mother also told officials a firearm may be missing from the home, and school officials couldn't find the boy in class. The school was then placed on lockdown. Officers arrived at both the school and at the boy's home to search for the weapon and student. Police were able to determine that all firearms were actually accounted for.
Police say the boy was found on a road near the Oshkosh Correctional Institution. Police took the boy to a medical facility were he is currently being treated for a pre-existing medical condition, as well as his mental health status.
Police have now found that the rest of the students at Oshkosh North High School were never in any danger. Nearly an hour after the lockdown was put in place, the Oshkosh Police Department advised North High School that the situation was resolved and the hard lockdown was lifted.
