Killer Instinct by Jennifer Barnes

killerCassie, Dean, Lia, Sloane, and Michael are 17-year-old FBI protégés in a secret program that trains gifted teens to solve criminal cases. Supposedly, they only work on cold cases, but when a grisly murder occurs on a nearby college campus, they immediately start working on the case, despite the FBI’s orders. What complicates matters is that the murderer is using the same methods as imprisoned serial killer Daniel Redding Dean’s father.
