Allegheny Township Police charged Cipriani-Baustert with four counts of giving alcohol to minors, three counts of luring minors into a car, three counts of corruption of minors, including one for allegedly giving a student an unspecified prescription drug, and one count of stalking.
The charges allegedly involve a 16-year-old girl and two male students, one 17 and one 18.
Cipriani-Baustert did not comment.
Her attorney, Matthew S. Faher of Vandergrift, declined to discuss the case because he said he just had received police documents outlining the accusations.
"I will be fully prepared at the preliminary hearing," he added. Her preliminary hearing is scheduled for June 1 in Vandergrift.
According to police documents, the high school's acting principal, Jeffrey Soles, called police shortly before 11 a.m. April 3 to "check the building" for Cipriani-Baustert who he had "let go" earlier on that day. She wasn't in the school or on school grounds.
Soles told police there were allegations that Cipriani-Baustert took students to the Pittsburgh Zoo during school hours without parental consent.
The 18-year-old told police he met Cipriani-Baustert when he was in the in-school suspension room that she was supervising.
Police said he and the girl started to work for Cipriani-Baustert at her business.
Police allege Cipriani-Baustert took vodka to the suspension room Feb. 18 for one of the boys, who allegedly mixed it with a drink he bought in a school vending machine.
She also allowed the girl and a boy access to a 12-pack of beer at her house March 7, police allege.
According to the affidavit, the woman picked up the three students at the Hyde Park Plaza shopping center near the school, took them to the Denny's restaurant in New Kensington for breakfast, and then drove them to the Pittsburgh Zoo and one of Pittsburgh's Inclines before returning them to the area of the school at 3 p.m.
The 18-year-old told police that Cipriani-Baustert "constantly text messaged" him and earlier this month asked him to meet her at the shopping center. He said he instead rode the bus home.
She also allegedly went to where he was working in North Apollo and refused to leave before he called Kiski police.
According to the police document, at about noon April 2, Cipriani-Baustert called the in-school suspension supervisor to say there was a paperwork mistake and the 16-year-old was to have an early dismissal.
Police allege the suspect took the girl to the Bronze Effects tanning salon in Washington Township. The girl then allegedly accompanied Cipriani-Baustert to her doctor's office in Harrison.
