Gyakuten Saiban: Sono "Shinjitsu", Igi Ari! Season 2

Synopsis

One year prior to her first meeting with Phoenix, Mia takes on her first client; a death row convict named Terry Fawles who is accused of murdering policewoman Valerie Hawthorne, with the assistance of her senior, Diego Armando. Taking the prosecution, a young Edgeworth explains how Fawles escaped from prison to meet up with Valerie, whose testimony accusing him of killing a hostage put him on death row five years ago. After Gumshoe details how Valerie was found stabbed in the trunk of a stolen car after meeting with Fawles on a bridge, presenting a photograph of the two meeting, Mia asks to cross-examine the one who took the picture, Melissa Foster. Noticing the inconsistencies in Foster's testimony, Mia suspects that Foster murdered Valerie and hid her in the trunk before imitating her and meeting with Fawles in order to frame him. It is then that Diego identifies Foster as the hostage who allegedly died five years ago, Valerie's sister Dahlia.
