A Council Bluffs newlywed returned from Georgia on Sunday night to tell detectives what she knows about the shooting death of Anthony Walker.

Rachel Lewis, 22, turned herself in to authorities on Sunday night. She was wanted as a material witness in the shooting death of Walker on March 7.

Lewis had been in Atlanta with murder suspect Markis Davis, who headed south to hide out at his mother’s house, said Council Bluffs Police Sgt. David Dawson. Davis’ mother instead called police and told her son to go back to Council Bluffs, Dawson said.

Davis, 30, turned himself into authorities on March 16, but not before marrying Lewis in hopes that she won’t be asked to testify against him in court, Dawson said. Lewis has not been charged with any crime and was only wanted for questioning.

According to Davis’ arrest affidavit, Lewis was not at the crime scene on the 100 block of Glen Avenue, but she did have phone conversations with Davis about the alleged plan to rob Walker and Patrick Schulz, who was also shot during the reported robbery attempt. Schulz survived a gunshot to the arm.

Dawson said Lewis attempted to talk Davis out of the plan.
