PITTSBURGH — A woman has pleaded guilty to taking part in a shooting death during a 2013 home invasion in a Pittsburgh suburb.

Twenty-three-year-old Kexuana Sayles entered the plea Tuesday to third-degree murder, robbery and conspiracy as opening statements were about to begin in her Allegheny County trial.

Prosecutors said she and three other people planned to rob Thomas Cassano, who was found shot to death in Coraopolis in November 2013. Deputy District Attorney Kevin Chernosky told the judge that she knew the victim and her job was to open the door for the others.

Sayles is to be sentenced May 2. Three co-defendants — Tanika Paul, Bradley Kemp and Rasheim Wallace — are still awaiting trial.
