"Another one?" Namjoon groaned and pulled at his hair, "I don't want to hear anymore,"

Taehyung placed the file on his Sergeants desk, "Sorry, Sarge," He said, "This guy just doesn't take a break,"

Namjoon sighed and lifted his head. He opened the file and tried not to wince at the front page.

"Any ID on her?"

"Jimin's looking into it, but..."

Namjoon smiled, "But his wife is due any day. At least something good is happening,"

Taehyung paused, "We know that the victim is around the same age as Bee again so he's worried,"

Namjoon looked back down at the pictures of the mutilated body in front of him. He pushed them to the side so he could look at the report.

"Female, around twenty seven years of age, found tied to a bed in Hotel Rivera. Visual inspection confirms missing lungs and left leg,"

He pinched the bridge of his nose and looked up, "Have you been to the scene?"

Taehyung nodded, "Jimin wrote the report but we were both there. I'll be honest, Sarge, we need help. This is the sixth body in two months. The public are calling this guy Dr Frankenstein Junior,"

"What did the FBI say? I haven't read your report yet and the Captain's been busy today,"

"They think the same as us," Taehyung sank into the seat at Namjoon's desk, "We got ourselves a copycat. They're going to send us an agent to assist us and get us quicker access to files and warrants, but that's all,"

"That's not all," Both Namjoon and Taehyung turned as their captain appeared, "I just got off the phone with Agent Kim Seokjin. They are conducting their own search but allowing us to continue," He sighed, "The more people on this, the better," He leaned forward, "We need to talk to Doctor Min Yoongi. It's the best option we've got right now,"

"Bringing him in is too dangerous, Sir," Taehyung gasped.

"Captain Jung," Namjoon looked up at him, "Did the FBI not already do that?"

The Captain crossed his arms, "They don't have anyone able to talk to him,"

"So how would we be able to talk to him?"

"The agent the FBI is sending is new," Captain Jung replied, "Maybe we can send her,"

Daisy stepped into her superiors office nervously.

"You wanted to see me, Agent Kim?"

Agent Kim smiled at her, "Call me Seokjin, it's fine. And don't look so nervous, you're not in trouble. I'm assigning you to your first case,"

Daisy couldn't help but smile, "Thank you, Sir!"

"I'm sure you're aware of the rising victim count in the latest serial killer case?"

She nodded, excited.

"The FBI are going to be working closely with the Detectives in the area for this case, and your assignment is to assist them in any way necessary, as well as keeping me up to date on their progress," He straightened behind his desk, "This is not a competition or race between the FBI and the Police Department. This is an urgent case where we need to work together to catch this psychopath,"

"Yes, Sir," Daisy was buzzing with nervous excitement.

Seokjin slid a thick manila file across his desk, "Here is your case file, share it with the detectives as it contains our profilers opinion on this killer. Good luck, Agent Song,"

"Thank you Sir! I'll go straight to the police department!"

Daisy grabbed the file and rushed to her desk, where she snatched her bag from the drawer and rooted inside for her keys. She straightened her badge and double-checked her gun and exited the building into the underground parking lot.

Once inside the car, she flicked the overhead light on and opened the file.

There were grisly pictures of dismembered bodies with organs missing and limbs hacked off right in the first clear plastic folder. She flipped it over, having already studied them and not wanting to lose her breakfast.

The next page was a list of victims, including names, ages, sex, place, time and cause of death and autopsy results. There were six pages with each side filled out. Two whole sides for each victim.

The next information was what she was looking for.

The FBI profile of the murderer. The very information she needed to get inside this serial killer's head.
