A 65-year-old Norcross woman who was the subject of a police alert Thursday has been found unharmed and is being reunited with her family, Gwinnett County police said Friday.

Baldwin police spotted Renee Antoinette Harris' car as she was driving in Habersham County around 9 p.m. Thursday. A family member was notified and went to pick her up, police said.

Harris, who police said has undiagnosed dementia and memory loss, had left Emory Eastside Medical Center Wednesday morning. Her husband, James, had undergone surgery at the hospital. She never returned to their Norcross home, and around 10 p.m. that night she called her husband from her cell phone to say she was lost in the Gainesville area.

At 9 a.m. Thursday, she called her husband again to say she was still lost. Then her cell phone was dead and her husband was unable to reach her. The Gwinnett County Police Department on Thursday issued an emergency alert for a missing elderly or disabled person, a Mattie's Call, with a description of Harris and her car.
