"So, it's a serial killer," Aiden stated as she studied the six pictures on the table.

After discovering five more bodies with the same characteristics as Danny's DB, Mac had called in the whole team to work on what was now officially the biggest case in the entire city.

"It would seem that way," he said, his gaze held by the words printed on each of the victims' backs. Six pairs of black bruises with the accusation 'cop killer' stared back at him, urging him to understand their true meaning. "So let's see how far we can go before the feds arrive to play in our turf. What do we know about them?"

Stella started from the left and grabbed the pictures of the two DB's she'd been working on.

"Margaret Stuton, age 47 and Xavier Stuton, age 48," she said, holding the glossy pictures of the couple. "Married for twenty five years. A neighbour that was supposed to have lunch with them yesterday found them dead, seating on their living room's couch. Restriction marks, similar to the ones Danny found on Trevor were present on both bodies. COD so far is being pegged as strangulation, but we're still waiting on the autopsy results."

Aiden grabbed the new two pictures, hers and Mac's case, another couple.

"Samantha and Louis Emmertton, age 46 and 49, married for fifteen years. The uniforms passing down the old TA Bridge reported a parked car. The bodies were found inside, seated on the front seats, seat belts on. The marks on both wrists and ankles are consistent with both Trevor Mils and the Stutons. COD is yet to determine."

Flack grabbed the next picture, belaying what the CSI working the case had told him.

"Female DB, middle age, found in a dumpster in a corner between the 166th Street and Broadway. COD was a single blow to the head. She'd been lying downstairs for three days, waiting to be IDed."

Danny grabbed the last picture.

"Trevor Mils, age 45, found in the Harlem River, just pass Spuyten Duyvil Creek. COD is yet to be determined, but Sheldon was leaning towards heart failure. If it weren't for the rope marks, it had natural cause written all over it. He was trying to catch any lingering cyanosis in the fingertips when the UV light caught the bruising on the back and…" he trailed off when he spotted the blond man in a suit staring at him from the doorway of the common room. "You liking the show or should we just refund you the ticket money?"

All four heads turned to the door, spotting the intruder to their meeting. Mac took the lead. "Can we help you?" He asked in a deceiving cordial tone.

"I'm sorry… I must've come across a little stalk-ish," the man apologized, even though everyone in that room, experienced with interrogations, knew he wasn't being sincere. "My name is Donauh, John Donauh. I'm with the Bureau," he said, offering a hand to greet Mac. "They send me over to help out in your investigation."

"Damn… that was fast," Aiden let out between closed teeth.
