WAGONER COUNTY, Okla. – An April Fools’ prank landed a teen in jail and her boyfriend in the hospital Monday.

Deputies said they are still trying to piece together the crime scene but said they believe 18-year-old Tori Wheeler told her boyfriend she was pregnant as an April Fools’ joke.

Upon hearing the news, her boyfriend got very angry.

Police said that’s when she pulled out a knife and threatened him, again, she said in jest.

Things only got worse from there.

The fight escalated, ultimately resulting in Wheeler cutting her boyfriend’s throat with the knife and biting him twice.

The boyfriend is expected to be OK.

Wheeler was arrested and is charged with assault with a deadly weapon.
