After arresting a Missouri man who logged his alleged thefts in a journal, authorities filled in his final entry: “02/06/2019 – Arrested Muahahaha,” according to a picture from the department.

The offbeat arrest was featured in the Ballwin Police Department’s “Weekly Roundup” report on Monday. A picture of the suspect’s journal, along with the police’s entry, was posted on the department’s Facebook page.

The suspect-- who was not identified-- was arrested Wednesday after officers “observed him and his backpack full of alcohol clanging down the sidewalk,” police said. He was subsequently identified as the “serial thief” mentioned in previously roundups, “who keeps a journal of his crimes” and has stolen alcohol from local businesses.
