He slipped right in front of the couple to get to the tunnel ahead of them. There were barely seconds before they would turn round the corner, so the gunrunner needed to act fast. The cross was in his hand, he was twirling it, looking for a place where they would surely find it.
One of the industrial lights was blinking. He felt annoyed at it, before realizing that if that drew his attention, surely they would look to it to.
Rushing to the spot, he placed the cross right in the middle of the cone of light and hugged the walls and shadows mere moments before the couple turned the corner. He was safe, hidden from their Mind's Eye.
As they approached the place, he carefully circled them. They were careful, checking behind and in front, watching each other's backs. If they didn't take the bait, he wouldn't get the drop on them. And then the old geezers would run in with their hunting rifles...
- What's that...? - said the girl, pointing the gun at the object on the ground. - Is that...?
The guy, the protector he was, walked forward, while the girl stayed back a bit.
Just as the guy bent down for the cross, Diego slipped from out of the shadows and hit the girl on the back of her head with the handle of the knife.
Her body slumped to the ground, with and "ummph" and a thump. The guy started turning, and Diego flung himself at him, grabbing him by the head and hitting it against the wall. Not loosing a second, he grabbed her by the arm and him by the leg and rapidly pulled them away from the scene, into a side tunnel.
He stopped only when he was far enough... And saw a corpse slumped against the wall of the tunnel.
- What the hell...? - he whispered under his breath. He pulled out the phone and took a picture, before starting to type rapidly.
"4 down, 2 left w/ rifles. 2 more in the tunnels, shot. Not my handywork. Everyone be careful. Need help with last 2. Collector Tunnl A4"
He put away the phone and crouched in front of the corpse.
