Bomb Alert on Grimsborough is a case featured in Criminal Case, appearing as the thirteenth case of the game as well as the city of Grimsborough. It takes place in the Financial Center, a district based in Grimsborough.
Jones and the player went to the park to have their lunch and suddenly they heard an explosion at the other side of the park. They went there to discover the body of Henry Crosby who was found dead with his body heavily damaged. Thinking this bombing was planned, they started the murder investigation. The killer turned out to be an explosives expert and the victim's old friend named Donald Byrd.
Upon confronting him, Donald had managed to slip out of the police's sight before carrying out a suicide bombing in Cooper Park. Although he never made a confession, Donald may have killed Henry for testifying against him after he was charged with war crimes and then admitted to an institute for the criminally insane. Both Henry and Donald served in the US Military sometime in their lives.
