Sixty by Yvette Walker (Linda Radcliffe Chronicles #1)

"Linda, I know you won't remember me, but my daughter was killed by Mayfield Sherman."
Christian reporter Linda Radcliffe felt like someone kicked her in the gut. Mayfield Sherman? Lord! That monster was put to death several years ago, but not before he killed several women. He'd made a stop in Oklahoma, right on Linda's reporting beat. But she'd left, and Sherman was a big part of the reason. She had read the police files. She had seen the photos. Twenty years later, she's back to help a family she once covered. When she meets her old colleague, now the editor of the town paper, feelings once dampened begin to rise again.
