On page 8 in Magog #2 (Dec. 2009), a yet-unnamed illegal arms dealer discusses with Chelsea (his assistant?) the recent killing of 3 of their agents. Chelsea believes one of their clients, Mr. Sunderland, might have something to do with it. The arms dealer decides to visit Mr. Sunderland. He asks Chelsea: "His contact?"
Chelsea answers, "Um . . . 0274? That Detective . . . Bannigan?"
The arms dealer dials Detective Bannigan's phone number. In the next panel we see Detective Bannigan's phone ringing. Unfortunately for him, Detective Bannigan is dead. His body has been mutilated and his arm detached. He was reading the book The Gold Bug by Edgar Allan Poe when he was murdered.
Not long after this, Magog is working out in the gym of the Justice Society of America headquarters when his teammate, Jay Garrick ("The Flash") comes to deliver bad news. Garrick tells Magog that David Bannigan was recently found murdered. Garrick somehow knew that Magog knew Bannigan.
Magog briefly explains that he and Bannigan served together in the Marines. Bannigan was a sergeant, 2nd Platoon out of the 81st. Bannigan and Magog (back then just David Reid, a regular soldier) had not been particularly close. But the Flash is worried that Magog might do something rash, like look for payback or revenge over Bannigan's murder.
Magog fakes an emotional response, which is what he thinks the Flash wants to see, and then leaves to investigate as soon as he can. He doesn't have an emotional attachment to Bannigan, but he does want to find out if this murder ties into his ongoing investigation into an emerging global criminal organization.
Later (page 12) Magog thinks about David Bannigan: "I skip the funeral. Didn't much like the man when he was alive. Dead doesn't change anything. Corrupt is corrupt. I give Axel a heads up, just in case he wants to pay his respects. We both get a good laugh out of that."
