The New Detectives

S09:É08 - S09:E08 - Out to Kill

Blood was found in front of a woman's abandoned vehicle. Police get a tip about a man who is impersonating police officers. Investigators get tire samples of the man's car and find blood matching the dead woman. A boy is reported missing. His friends reported seeing the boy with a man. A hotel clerk tells of a man in her hotel who fits the description. Police find hair in the man's car that match the boy's DNA. Sometimes witnesses are the only link between criminals and forensic experts.
