Saving Sammy (S04E05)

Rush mixes pleasure with business when her boyfriend, Joseph (Kenneth Johnson), asks her to reopen a 2003 case involving an autistic boy named Brent Harding (Cole Peterson) who witnessed his parents' murder. Brent's photographic memory and his inability to lie lead Rush to a series of clues and suspects, including Brent's sister, who lied about where her brother was on the night of the murders, a bully at school and a corrupt school administrator. Now, Rush and the team must decipher which facts are real and which could possibly be figments of Brent's imagination. (Warner Bros. UK)
