A customer at an impasse with Capital One over a disputed debt is facing a half-decade in federal prison after allegedly vowing to assassinate those executives he held responsible for having “ruined” his life.

In a December 12 email, Houston, Texas resident and budding beef jerky impresario Taylor Bullard told the bank’s collections agency that he had already paid the amount in question and that they were chasing him in error, according to an FBI affidavit unsealed upon his arrest eight days later.

“Call me before I show up to one of their locations with a machete and gasoline,” Bullard wrote, according to a screenshot of the email included in the affidavit. “You have ruined my ability to buy a home. I’m 34 with a 100k+ job and it’s time I target the people and companies that have ruined my ability to live the life I deserve. I will be coming after your executive team personally. Please call me before I do things that are unforgivable and will make your executive team question their life choices. Thank you, Taylor Bullard”

The affidavit says Bullard sent the note in response to an email from Capital One “urging [him] to create a payment plan to resolve his approximate $543 debt with the company.”
