Former student charged with killing Tara Grinstead

Channel 2 Action News has learned there is a major break in the case of a missing Georgia teacher who vanished more than 10 years ago.

Thursday, GBI said they'll provide an update on Tara Grinstead in a press conference in south Georgia.

Authorities never stopped investigating Grinstead's case, said Ricketson, who noted that her file had become the largest one in the Georgia Bureau of Investigation's 80-year history. Police found her cell phone and vehicle at her home, but her keys and purse were missing, according to AP.

She was reported missing went she failed to show up for work. The information gained from the interviews led agents to develop enough probable cause to get an arrest warrant for Duke, charging him with the murder of Grinstead.

However, a GBI statement of the case says, "The search for Grinstead's remains continues".

He said Duke was arrested Wednesday and is now in the Irwin County jail.

In a 2006 interview with the Atlanta-Journal Constitution, Grinstead's sister Anita Gattis said she believed her sister left with someone she knew.

Ricketson said Duke may face further charges in the case, but declined to comment further.

Witnesses say they last saw her at a beauty pageant and then at a friend's party.
