From no where the girl leapt up and ran, the older couple tried to escape into what he assumed was the living room, he adjusted his rifle and fired the shot. It had all become clear on how to send the message. From the range he shot at and the sound suppressor it would be nearly impossible to detect from anywhere further than a few hundred yards. The recoil of the rifle was nothing he wasn't used too. 

The bullet passed through the space between the apartment and his rifle, in a matter of moments. It pierced the window and exploded the wine bottle showering the trailing parent with the wine. It buried through the wall and planted its self into the elevator frame. 

He watched through his scope as the lights went out in the apartment and it all went quiet. He hopped that his message was received. He sat up and exposed himself, folding the blanket to carry it with him. He left the empty shell in the rifle so he didn't have too find it later. "Damn fine shooting if I say so myself." he chuckled softly. He sat for a moment all the tension melting, he reached into his pocket and pulled out a slightly crumpled pack of cigarettes, pulling the last one out he lit up. Sucking down the smoke greedily he gave a sigh of relief. 

His contact would be angry, but the message was still delivered. And he could sleep soundly. He'd killed women and children before, he saw their faces every night. Men, he didn't mind he supposed or at least he'd gotten used to them. He rarely saw their faces anymore.
