Events of Criminal Case

The Death of Rosa Wolf

Ash was the first suspect in this case. After Matt Barry was arrested for Rosa Wolf's murder, Jones and the player tried to interrogate Ash for information regarding the Vipers gang but Ash refused. This prompted the team to investigate the city's entrance for any trace Ash might have had left behind when he was arrested. The fingerprints on the gun matched Ash's (thanks to Alex), and the team thus hurried back to make him cooperate, but Ash was not willing to do so, even with fingerprints on a hand gun he dropped – grounds for the team to temporarily lock him up.

Into the Vipers' Nest

Ash returned as a suspect after the team found his dog tag in a toolbox in the crime scene. Upon interrogation, he said that he was not saddened by the victim's death since he was dumb and since he kept triggering his asthma for laughs.

Later on, Tony Marconi spilled that Ash became the gang's new leader after Salvador's death. Ash admitted he was happy to be the new boss but kept in mind that Tony was the true boss of the district.


  • Ash is one of the many suspects who appeared in two cases.
  • Ash's physical appearance on the mobile version of Criminal Case is different to some degree: he seems bulkier, and an oil stain is oddly visible on his jacket during the events of The Death of Rosa Wolf (see image here).
