As detectives continued to search for 30-year-old Sean Michael Yacks, the U.S. Marshals Violent Offender Task Force began assisting with the investigation. Members of the Task Force obtained information that Yacks was possibly staying in Mexico and they began working with Mexican authorities. On October 18, 2018, Mexican authorities located Yacks and took him into custody. He was then brought to the border and turned over to U.S. Customs and Border Protection Officers. Deputies with the Pima County Sheriff’s Department then took custody of Yacks and booked him into jail in Ajo, Arizona on his felony arrest warrant. Yacks is now awaiting transport back to Tucson, where he will be booked into the Pima County Jail. This arrest was made through the collaborative efforts of many different law enforcement agencies, including our partners across the border. A special thanks to everyone involved.
