Batman: Arkham Origins
During a Halloween Party at Wayne Manor, Ian Chase ended up causing a disturbance (presumably by harassing Clarissa Rodriguez, based on a comment made by Alfred), which forced Bruce Wayne to throw him out. Two months later, on Christmas, Chase, by that time a gang member to the Joker (who took over Black Mask's Gang) went to Crime Alley and proceeded to murder both Rodriguez and her fiancée, Horace Riley, by shooting her in the heart, and shooting him in the lung, respectively, coincidentally at the same spot that Bruce's parents had been murdered during a mugging during his childhood (it's implied that he did that out of a grudge from a unrequited love triangle, where Clarissa went with Horace instead of him). Although Chase managed to clean up the area by removing most of the bullet casings, he missed one inside of the grate. Batman, Bruce Wayne's alter ego, managed to uncover the murder and deduced Chase's role in their murder. Batman then tracked Chase down to the Industrial District, near the Sionis Steel Mill where Chase alongside other mobsters, were discussing his role in the murder (the dialogue suggested that he would have been the number one suspect in Riley and Rodriguez's murders, but could not be convicted without proof). Batman then ended up attacking Chase and nearly killing him due to his petty reason for committing the murders before Alfred calmed him down, and knocked Chase out to be arrested by the GCPD.
