To Catch a Killer by Sheryl Scarborough

Erin's mother was murdered. And Erin was there when it happened. She was just a toddler and was left in the house for days while her mother's body lay on the floor in a puddle of her own blood. But Erin survived.

Erin was raised by her mother's best friend, Rachel, who has always been overly protective. Rachel will not discuss Erin's mother or what happened. But it doesn't stop Rachel from wondering. Erin is drawn to forensics like her Uncle Victor whom she has never met. He works for the FBI and has written about his experiences in books that Erin has practically memorized.

Ultimately, Erin wants to solve her mom's murder, but she can only do so much as a student. She is fortunate to have an encouraging biology teacher, Miss Peters, who helps her dabble in forensic science. Erin was delivering some important materials to Miss P's house the night she finds her lying dead on the floor. Two dead bodies is too much for one lifetime.

That night Erin saw Journey Michaels near Miss P's house, too. Erin has been fascinated by Journey for a while, but what if he killed her favorite teacher? Her best friends Spam and Lysa have never understood Erin's attraction to Journey. They also worry about Erin's obsession with her mom's murder case.

So many questions to answer about the two murders with Erin the only obvious connection. There is much to keep the reader guessing, but it is well worth it.
