Fred Boyd, a former warrants officer for the police department, was being sought in connection with the death of Boyd's wife, Anniston Police Chief Layton McGrady said. Coroner Pat Brown said the victim was Carmella Boyd, 41, of Saks.
According to the police department's Facebook page, police believed the Boyd was driving a 2006 GMC Yukon.
Boyd is also suspected in a non-fatal attack on a Hobson City resident this morning, Calhoun County Sheriff's Office officials said.
Chief Deputy Matt Wade said Boyd reportedly showed up at the Hobson City resident's house Monday morning, knocked on the door, and fired a gun at a resident. The resident fired back, Wade said. Wade said an arrest warrant for attempted murder had been issued against Boyd in relation to the incident.
Anniston City Hall was on lockdown and the Anniston Police Department is under heightened security measures as police looked for Boyd.
McGrady said Boyd had not made specific threats against City Hall or the police department, but the measures were being taken as a precaution.
Police Capt. Shane Denham said Boyd, who resigned from the police department in 2011, had been working as a security guard.
Police officers with assault rifles could be seen guarding City Hall and the police department during the search.
Around 11:40 a.m., the police department's Facebook page announced that the lockdown at the city buildings had ended.
Before noon, Wade told The Star that Boyd was in custody in Meridian, Miss. after turning himself in at a police department in Mississippi.
Boyd resigned from the department last year amid a certain amount of controversy. In his nearly two decades at the department, Boyd filed two EEOC complaints against his coworkers and supervisors. The EEOC dismissed both of them, ruling there was not sufficient evidence to prove that Anniston police officers discriminated against Boyd because he is black.
