Prison guard Albert James Turner Jr., accused of killing his wife and mother-in-law in Rosenberg, was captured Friday in Concord, N.C., after more than two months on the run, the U.S. Marshals Service said.

Turner, 45, was arrested without incident as he sat on a bench in a shopping mall around 12:45 p.m. Houston time, Rosenberg police said.

Turner is accused of fatally stabbing his wife, Keitha Frank Turner, 39, and his mother-in-law, Betty Jo Frank, 66, after an argument on Dec. 27. Both women died of stab wounds to their faces and necks — injuries inflicted in front of several of Turner's children, the U.S. Marshal's Service said.

One of the children called 911 after the slayings occurred at the home of Turner's in-laws in the 2400 block of Chestnut. The sounds of children screaming could be heard in the background of the 911 call.

Turner's father-in-law, pastor Gene Frank, who founded the Church of Living Waters and Living Water Christian School, was inside the home at the time of the killings and suffered minor injuries.

Turner, who worked at a Texas Department of Criminal Justice prison in Sugar Land, immediately fled the home. A few days later, his Honda Accord was found in the Chattahoochee River in Georgia.

The search had been focused around Atlanta as well as the Orlando, Fla., area, where Turner is known to have family.

Turner was added to the U.S. Marshal's 15 Most Wanted last week and his case was scheduled to be profiled nationally on America's Most Wanted Saturday night.

A tip led to Turner's arrest after an America's Most Wanted preview featuring Turner aired Friday morning on the Live with Regis and Kelly TV show as America's Most Wanted host John Walsh appeared to celebrate his program's 1,000th episode, the U.S. Marshal's Service said.

“Thanks to America's Most Wanted and a viewer tip, Turner will now get a different perspective of what it is like to be in a prison,” said John F. Clark, director of the U.S. Marshal's Service. “The fact that he committed horrible crimes in front of his children makes his capture even more satisfying.”

Turner will be extradited to Fort Bend County, where he will stand trial for the double slaying.

Rosenberg Police Chief Robert Gracia said the Frank family was notified of the arrest. “It's a good day in Rosenberg,” Gracia said. “We were notified by the Concord Police Department that they had arrested Turner, and we're in the process of working with the federal authorities at the U.S. Marshal's office to bring him back here to stand trial.”
