From what Nick was able to dig up on the ritual, all it takes is a death and a specific phrase. Anybody in the alley right now could serve as a sacrifice, except for the Murdergaunt.
Meredith brought her sword down heavily onto the demon, with another white flash of holy energy. The fiend ducked to the side, but still had a chunk carved out of his shoulder.
As Larry ran after the cultist, he opened himself up to the demon, which stabbed him as he ran past. The spike went right towards his heart, tearing through his clothes and every layer of the kevlar vest he was wearing, except for the last one. The light layer of anti-stab mail.
The cultist ducked under Larry's wild swing with the shotgun, however.
Lieutenant Quinn ran up to the edge of SUV. "Freeze, pol-" she started to shout, then a got a good look at the Murdergaunt. "Oh god, what the hell is that?" she said, bringing up her Glock and firing off two rounds instinctively. Both bullets hit the Murdergaunt in the forehead. Unfortunately, Quinn's weapon hadn't been blessed. The bullets impacted, flattened themselves, and then fell off, without even breaking the thing's skin.
Cade fired his shotgun, missing badly, however, as he tried to hit the creature without hitting Meredith.
The Murdergaunt whistled again, and smiled a horrible grin. It leaned over the SUV and stabbed Quinn in the left shoulder, and pulled her screaming into the alley, impaled on its spike. With it's other arm, it stabbed at Nick, the man who just shot it. The spear like arm penetrated into the side of his chest, and then Nick was pulled out of the car by it
Diego fired his shotgun, hitting the creature square in the chest with an explosive ten gauge shell. It penetrates, and blows out a significant portion of its chest. However, fiends are tougher than humans, and though it's looking poorly, it's still not dead.
The cultist pushes his captive away with a curse, and turns on Larry, quickly opened up a long gash on his arm with his knife. "Your deaths will serve as well as hers!" he snarls, and vicious expression on his face.
