(AP) — Two Oxford police officers have resigned amid more fallout from the arrest of a now former officer on murder charges.

No explanation was given for the departures, which Mayor Robyn Tannehill confirmed Wednesday to the Northeast Mississippi Daily Journal .

Tannehill says state law prohibits her from commenting on personnel issues.

After Tuesday’s Board of Aldermen’s meeting, Tannehill identified the officers as Ryan Winters and Collins Bryant. The resignations came shortly after the state attorney general’s office launched an internal investigation of the department at Tannehill’s request. That probe follows the arrest of former officer Matthew Kinne for the May 19 murder of 32-year-old Dominique Clayton, who was in a relationship with Kinne.

The Clayton family’s attorney, Carlos Moore, says he believes the resignations could be connected to Clayton’s death.
