Arrest made in cold-case disappearance of beauty queen Tara Grinstead

An arrest has been made in the 11-year-old cold-case disappearance of teacher and beauty queen Tara Grinstead.

The Georgia Bureau of Investigation announced at a press conference on Thursday afternoon that Ryan Alexander Duke has been charged with murder.

The teacher was last seen on Oct. 22, 2005, a few weeks shy of her 31st birthday -- and now her family finally has answers about what happened to her.

Though police searched extensively for her once she was reported missing and the case received attention from national news programs, Grinstead was never found.

According to The Atlanta Journal-Constitution, Anita Gattis said in a 2006 interview that her sister would not have left on her own the day she disappeared.

She said she believes her sister left with someone she knew on the night she disappeared. The house was locked, but her car was unlocked with $100 in the console and clay on the tires.

"Tara never left her car unlocked, and never drove on dirt roads," Gattis said.

According to Macon.com, her phone was left charging in her bedroom, but her keys and purse were missing. Both her cat and her dog were in the house.

Grinstead was well-known in her community. She was crowned Miss Tifton three times, and made it to several Miss Georgia pageants.

Gattis told The Atlanta Journal-Constitution that if someone had forced the beauty queen from her home, she would have used her well-trained voice she used in the talent portion of pageants to call for help.

She also mentioned that her sister took self-defense classes and certainly would have fought back if someone had attacked her. There was no evidence of a struggle at Grinstead's home.

Her disappearance is perhaps one of the most high-profile cases in Georgia's history, and it recently gained a large following through the Up and Vanished true crime podcast.

Few details about the arrest or killing were discussed at the press conference on Thursday. Authorities only mentioned that Duke was a student at Irwin County High School three years before Grinstead went missing.

"The search efforts never ceased," said J.T. Ricketson, special agent in charge of the GBI office.

Foreboding Kingsbury Run, shunned by the timid as the legend of its murders has grown, is indicated on this map by dots locating 10 of the 11 torso murders which have occurred there since Sept. 23, 1935. Police, delving into the lives of the mad murderer's victims, hope to uncover clues which will end the periodic killings. Discovery of photo negatives in the belongings of Edward Andra Ssy, first victim, show Andra Ssy in a strange room which, if identified, may provide a live lead, police believe. As the map shows, the murderer departed only twice from his custom of assailing victims in Kingsbury Run or adjacent Cuyahoga river valley.

U.S. labor leader Jimmy Hoffa is photographed at the Greater Pittsburgh Airport, Pennsylvania in this April 12, 1971 file photograph. Hoffa was switching planes from San Francisco, and was returning to the federal prison in Allenwood, Pennsylvania. Hoffa was let out of prison to visit his wife, who had been hospitalized with heart problems. FBI teams on May 25, 2006 sifted by hand through dirt from a chest-deep hole in the ground in an intense search for the body of Jimmy Hoffa three decades after his disappearance. Hoffa was last seen outside a Detroit-area restaurant where he was to meet New Jersey Teamsters' boss Anthony "Tony Pro" Provenzano, a member of the Genovese crime family, and a local Mafia captain, Anthony "Tony Jack" Giacalone. Hoffa was declared dead in 1982, and numerous books about his life have pinned his disappearance on mobsters who murdered him because they did not want him interfering with their close ties to the union.
