The Mississippi Supreme Court on Thursday declined to hear an appeal from Curtis Bennett, who was convicted in 2004 in Harrison County for the murder of his estranged wife.

The state Court of Appeals last August upheld Bennett’s murder conviction and life sentence.

Prosecutors said Bennett, 45, shot his wife, Connie, in the back three times Oct. 20, 2003, at the D’Iberville bank where she worked. She died at the scene.

According to the court record, Bennett testified that he didn’t remember killing her, saying his mind went blank after his wife allegedly told him in a cell phone call that she was interested in someone else.

The court record showed Bennett obtained a check for more than $100,000 from the couple’s home equity credit line four days before the killing. Prosecutors said Bennett drove to the bank with a shotgun, calmly walked through the bank looking for his wife while threatening other employees, found his wife and shot her three times, and then fled.
