(CNN) The mother of Texas death row inmate Rodney Reed, who is scheduled to be executed next week, says she knows he'll be a free man if he gets a new trial.

"If he gets a fair trial, he'll be home with us," Sandra Reed told CNN.

Rodney Reed was sentenced to death more than 20 years ago for the 1996 murder of 19-year-old Stacey Stites in Bastrop, Texas. Police said he assaulted, raped and strangled her. Reed said he's innocent, but the prosecution claims there's overwhelming evidence he's guilty.

Recently, celebrities, religious leaders and lawmakers began calling for a halt to his execution after his attorneys pointed to new witness accounts and evidence they claim exonerates him.

"All we have to do is get justice out the street and bring it back into the courtroom where it needs to be," Rodrick Reed, his brother, told CNN. "And Rodney Reed will be free and exonerated from this crime."
