Trish Colletti is the main antagonist in the facebook game Criminal Case third episode The Grim Butcher
Trish is Raoul Colletti's daughter and used to assist her father in the Colletti butchery. She was also in a relationship with Raoul's apprentice, Raphael Soza.
Trish was called into the investigation the moment Raoul informed David Jones and the player she had the keys to the warehouse. All Trish made clear was that Jennifer was a flirt, and neither Trish nor Jennifer were friends.
Trish was approached by the team a second time after the team found pages torn from Jennifer's diary in which Jennifer refused to talk to Raphael due to him being in a relationship with Trish. Trish did not like what the team asked her as Trish knew Raphael loved her and would never flirt with Jennifer.
Trish was guilty of the heinous murder when the killer's attributes incriminated her as Jennifer's killer. Raoul refused to protect Trish as the police had enough evidence to prove Trish's involvement of the murder but as the team arrested Trish, she opened up the reason why Jennifer's death was warranted—Trish found out Jennifer slept with Raphael and could not afford Jennifer to get away with it given Raoul's panicking every time Jennifer came to the Colletti Butchery. Trish kidnapped Jennifer, and then discreetly tortured her and butchered her up like a pig while no one was watching.
Due to the heinous nature of the crime and the psychological disorders she demonstrated in the murder, Judge Hall tried Trish as an adult but Trish countered that she did it for love because she knew Raphael was being brainwashed by Jennifer and she knew she had to act, which were grounds for a lifetime jail sentence with psychological monitoring and eligibility for parole in 40 years.
