MADISON (AP) — A man has been arrested and charged in the death of a Tennessee woman found stabbed to death at a counseling business.

Brian D. Conley, 31, is charged with the “brutal murder” of Melissa Hamilton, who was found dead early Wednesday, Metro Nashville police said in a statement.

Surveillance video shows Conley entering Crossroads Counseling in Madison at about 7:30 p.m. Tuesday, when the group counseling session she was working with ended, news outlets report, citing another police statement. Hamilton and Conley had a “brief interaction” before the center’s lights were turned off and Conley left through a rear exit, police said. There’s no indication that he was a client at the center, which provides domestic violence and alcohol and drug treatment counseling, sometimes to court-appointed clients. There’s also no indication that Conley knew Hamilton, police said.

Hours later, Hamilton’s husband of 25 years called police to say that his wife had never come home from work. Responding officers found Hamilton, the center’s assistant director, dead in a back office of the business.

Conley was arrested Thursday just outside of the Madison Public Library, which sits directly across from the counseling center. It’s unclear if he has a lawyer. His right hand had a wound consistent with Hamilton’s stab wounds, police said.
