A Connecticut woman, convinced that her boyfriend had been cheating on her with one of her friends, allegedly keyed each of their cars and punctured their tires. Stamford Police say they established the motive for the crime after trying to make sense of the word “wore” scratched into the paint of the woman’s car and realizing that the culprit was just atrocious at spelling.

Shannon Csapilla, 20, was charged with criminal mischief Thursday, the Stamford Advocate reports. She denied damaging the two cars in an interview at police headquarters, but later incriminated herself immediately after leaving the building: she Snapchatted a photo of police HQ with the caption “Stamford police have nothing on me.”

“Unbeknownst to her, we did have enough and we obtained two arrest warrants from a judge and took her into custody at her home,” Lt. Diedrich Hohn of the Stamford PD told the Advocate.

It seems one of the people to whom she sent the photo ratted her out. The message, combined with some angry texts to her (now ex-) boyfriend and his testimony that she admitted to keying his car, were enough to get her arrested.

Boo, you wore.
