In a freezer at the Police Department in Lufkin, Tex., there is a half-gallon container of Blue Bell ice cream in an evidence bag — Exhibit A from a cringe-inducing video that drew widespread attention.

In the video, a teenage girl can be seen removing the tub of ice cream from a store freezer, lifting the lid, licking the top of the ice cream, then closing the lid and putting the container back before walking away.

Soon after the video was posted to Instagram, on June 28, social media erupted in shock and disgust. Some posted copycat videos on Twitter and others implored Blue Bell to use tamper-resistant foils under the lids of its ice cream tubs.

In an emailed statement, Blue Bell said it identified a Walmart in Lufkin, about 120 miles northeast of Houston, “as the store where the malicious act of food tampering took place.”
