A security guard at McKeesport Area High School is accused of having an inappropriate relationship with a student.
Allegheny County Police say an investigation began last month into a reported sexual assault involving a 17-year-old boy and a 24-year-old security guard.
Alexis Brown allegedly initiated the relationship with the student through social media.
Police found a stolen 9 mm pistol in Brown’s residence during a search.
Brown was arrested Monday and is facing institutional sexual assault, corruption of minors and unlawful contact with minors.
She also faces a separate charge of stolen property for the recovered firearm.
