Murder In Mind - James F. David

Singer McKenzie's photographic memory had been more of a curse than a gift, until he is recruited into a classified FBI program using experimental neurotechnology. Linked to murder victims, Singer can experience the last moments of their lives. Soon, Singer is on the trail of two serial killers, not knowing he is also being hunted. But when he is unwittingly linked to a murderer, he experiences the dark side of the technology and fears he is becoming one of the monsters he is hunting.
