The indictment alleges the conspiracy by Turner and Sherra Wright began in April of 2010 and that both were at Callis Cutoff and Hacks Cross Road where Lorenzen Wright's body was later found.
The Memphis Bucks star was last seen alive on July 18, 2010-when he was leaving Sherra Wright's home.
The body of Wright, 34, was found in southeast Memphis on July 28, 2010 - 10 days after he was reported missing.
Sherra Wright was arrested Friday evening, December 15, by federal marshals in Murrieta, California on the indictment by a Shelby County grand jury and remained in custody there Saturday awaiting extradition proceedings.
During the investigation police uncovered an emergency call placed from Wright's mobile phone in which 11 gunshots can be heard.
Wright's mother told The Commercial Appeal that a police official told her Wright-Robinson will be charged with first-degree murder, the same charge Turner faces. He was shot multiple times.More news: Two killed in San Diego plane crash
She was criticized for burning through almost a million dollars of her ex-husband's life insurance money that was taken out just six months before Lorenzen's death.
The body was found in a field near some woods in the height of summer, complicating the investigation because evidence had likely deteriorated in the heat.
Dispatchers said they didn't alert patrol officers or commanders because they couldn't confirm it came from their jurisdiction.
The charges were announced at a press conference held by Memphis Police Director Michael Rallings earlier this morning. An autopsy report showed bullet fragments were lodged in Wright's skull, chest and right forearm.
The 6-foot-11 Wright played for the Memphis Grizzlies and four other National Basketball Association teams as a forward and center over 13 seasons before retiring in 2009.
Lorenzen Wright's murder remained one of Memphis police's highest-profile cold cases until investigators found a murder weapon in MS last month. He averaged 8 points per game and more than 6 rebounds per game during his career.
