Brenda Delgado’s crime was so heinous, she became the only woman on the FBI’s 10 Most-Wanted List (and the 9th woman ever) until she was caught in 2016.

The dental-hygienist-in-training hired two people to murder pediatric dentist Kendra Hatcher, who was dating her ex-boyfriend at the time: another dental hygienist to drive the getaway car, and a hitman to commit the murder.

In order to convince hitman to pull the trigger, Delgado allegedly told him she was connected to Mexican drug cartels and could get him a supply of drugs in return for offing her ex-boyfriend’s new flame. Jealous dentists and the promise of drugs turned out to be a deadly combination.
