Take a look @ issue #100 (July 2012) of Image Comics' "The Walking Dead", revealing the person killed by 'Negan' from 'Rick Grimes' group of survivors, in a sequence adapted for the Season Finale of AMC's "The Walking Dead":
"...the 'Saviors' line up the survivors from the van ('Rick', 'Carl', 'Glenn', 'Maggie', 'Sophia', 'Michonne' and 'Heath') on their knees before 'Negan'.
"Negan says he wants revenge for the dead Saviors that Rick and his people killed. Negan then dictates the terms for the group's survival; everything in the 'Alexandria Safe-Zone' now belongs to the Saviors. Negan further states that there is a new world order and that Rick and his people will now follow Negan or die.
"Negan then tells Rick that he is going to kill one of the group to show Rick's people that he is in charge. Negan introduces his weapon of choice for the execution: 'Lucille' - a baseball bat wrapped in barbed wire.
"After a long narrative from Negan about who should be killed with Lucille, Negan randomly picks Glenn as his victim. Maggie panics, as Glenn begs Negan not to kill him.
"Rick tries to intervene, but Negan snaps at Rick, telling him that there are fifty men surrounding them and they will all die if they try to stop Glenn's execution. Rick and the others remain silent and watch in horror and cry with bowed heads as Negan smashes Glenn's head in with Lucille.
The first blow fractures Glenn's skull and pops out an eye. Everyone cries, looking horrified and angry at Negan. Negan then taunts the still conscious and now brain-damaged Glenn, who reaches out and calls for Maggie.
Negan then repeatedly and brutally smashes Lucille into Glenn's head, leaving a mass of broken bone, smashed brains, and spattered blood.
"Negan informs Rick and his group that The Saviors will be back in one week to collect half of everything in their community. He turns around, leaving the survivors with Glenn's mangled corpse..."
