Officers said Jones, 26, and the man she's accused of performing a sex act on, Jeremiah Isiah Robinson, 35, were wanted for an unnatural and lascivious act.

Jones allegedly performed the sex act on Robinson at the courthouse on Jan. 31 and posted a video of it on social media with the caption "I just found a way to get out of trouble." Courthouse administrators confirmed a graphic video of the sex act took place in the hallway during business hours.

Robinson turned himself into police on Feb. 7. He is charged with committing a unnatural and lascivious act.
