Seamus was an arms dealer who worked for SOMBRA and supplied weapons to rebel leaders in the Sahara Region. He was married to Fiona Cummings and had a son, Damien Cummings, who died by a gunshot. Seamus had dark graying brown hair and green eyes. He donned a navy blue shirt and gray suit. He also wore a gold chain and had a phone in his suit pocket.
Seamus was found on Dubai's rooftop golf course with a bullet wound in his chest. According to Angela, Seamus was shot point-blank with a semi-automatic 45-caliber pistol. She found his gun holster was empty, which meant he was killed with his own gun. Angela also found he received a second-degree burn to his face while alive, and was caused by hot coffee. She believed the killer threw it in his face as a distraction before firing the gun, which meant the killer drinks coffee.
Jack and the player managed to find the victim's gun in the slums of Dubai. It was sent off to Lars for an analysis, and he managed to find traces of oud oil on the trigger. Jack had no idea what it was, so Lars explained it was a rare body oil, and expensive to boot. This meant that the killer wears oud oil.
Killer and motives
The killer turned out to be the victim's wife named Fiona Cummings.
Jack assumed Fiona killed her husband because he was cheating on her with popstar Vanna Alabama. Fiona kept denying her actions of killing her husband until Jack pulled the trigger with the evidence of her using her husband’s own gun to kill him and finding her earring back at the same place the weapon was. Fiona finally confessed to the murder, but claimed she did it because her husband had killed their son, Damien. Fiona explained that she was told the murder had been a drive-by at the wrong place and the wrong time. She had worked hard to rebuild her life due to how much the event destroyed her, but she found out the event was a lie a few months before. Fiona confessed that her son had actually been playing with Seamus's gun, only to accidentally shoot himself with the forbidden firearm and the latter covered it up. Jack was understanding of her situation, but told her that it did not justify murder and sent her to trial.
During the trial, Judge Adaku initially asked Fiona how the golf course was when she murdered her husband rather than what she thought about her actions. Fiona was shocked when he asked her that question and asked him if he had no soul because of what she had been through. The judge reminded her of the saying "you live by the fire, you die by the fire," and he sentenced her to 10 years in prison.
