| Hoffman Estates High School, located about 31 miles northwest 
				of Chicago, said on its website that the package was located on 
				the outer perimeter of the campus.
 At the time of the discovery, the high school was serving as one 
				of the host sites for the Illinois High School Association girls 
				state tennis tournament
 
 The brief lockdown came on the second day of the closure of a 
				school in the Chicago suburb of Skokie while police investigate 
				threatening posts sent to students via Instagram, a social media 
				platform, according to the website for McCracken Middle School.
 
 The school called the posts "inappropriate and threatening."
