After arriving at the station, Gideon and Morgan went to introduce themselves to the lead detective so that the four magicals could get a look at the Black tapestry. They found themselves in a secluded storage cupboard and Luna cast a mild muggle repellent charm to make sure that none of the numerous muggles would get hurt.
Hermione's arm was throbbing as she opened up the tapestry but she ignored it, the case was more important.
"Okay, so we are looking for Bellatrix, Narcissa and Andromeda, because their brother will be near them." This was said more for Spencer's benefit, however talking also distracted Hermione from the pain in her arm.
All four started looking and unsurprisingly Spencer was the first to find them. "Here," he pointed two the names. Hermione followed the line for siblings until she got to the fourth branch.
"Castor Black, it doesn't say a middle name so if they changed their name, it will either be an anagram or somehow related to a plant or star."
"Why a plant, Mione? The Blacks stick to stars." Neville questioned, confused at the logic.
"The Blacks denounced him when they found out he was a squib, he may prefer to use a different pureblood naming tradition, the next most common is flower names."
This made sense to all of the occupants, so they quickly put away the tapestry, removed the charms and went to find the other members of Spencer's team.
They entered the conference room where the rest of the team and Detective Gordon, the lead detective were. "More of yours I suppose?"
"Detective Gordon, these are SSA Dr. Spencer Reid, Hermione Granger-Reid, Luna Lovegood and Neville Longbottom, they're here to help as well." Hotch answered, clearly uncomfortable with having to introduce civilians as part of the team but knowing the necessity of it.
"How come only one of 'em is an agent?" Detective Gordon was curious, as well as slightly annoyed. They were bringing in civilians to help investigate a cop killer, and the case was getting to him.
"Detective Gordon, I have only recently been released from hospital under the stipulation of constant supervision for the next week at least, so when my husband and uncle were called in to help on your case I needed to come with them for medical reasons. Aside from that, the person that you are looking for was born and raised until the age of eleven into an extremely exclusive community, which myself, Neville and Luna are also a part of. I understand that you are stressed, I know that this case is hitting far too close to home for comfort, but please remember that we are here to help, even if our being here at all is considered rather unorthodox." Hermione said all this is a firm but understanding tone, that everyone could see did more to sooth the detective's frayed nerves than anything they could have said.
"Alright," the detective conceded nodding, "how can you help?"
This time Luna spoke up, "the person you are looking for was named Castor Black when he was part of our community, he may have changed his name, but we think his name will either be an anagram, a star name or a plant name, sticking with traditions from within our community. We need to find out which he has used, but I can guarantee you that he will be extremely dangerous, he will also most likely have a greater-than-thou attitude and aristocratic leanings."
"He will be in his late thirties but may only look as though he is in his twenties," Neville spoke up gaining confidence from the detective's ability to listen without interrupting. "He may even have applied for a job with the police, but he most likely failed due to his attitude and unwillingness to listen to orders."
"He will most likely live in the area surrounding the congress hotel due to it's connection to our community. I wouldn't be surprised to find that he lived in or next to the hotel. This may seem really odd, but he will most likely use words such as muggle, blood traitor and mudblood when you talk to him, all the while sprouting off about the superiority of purebloods. He may even mention someone called 'the dark lord'. It's not that he has made up his own language its that he was raised in our community by a family known for its long standing past in the community." Hermione finished for her friends.
The other occupants in the room were slightly in awe at the ability of the teens create a profile that professionally that left out the use of magic. With a look Hotch and Gideon acknowledged that all three would be an asset to the team.
"Okay, so how do we know what name this guy uses?" the detective asked after a beat, impressed with how the teens were conducting themselves.
"That's where our team comes in," said JJ, "we will contact our technical analyst using the parameters given to us by these three to find the name he uses now as well as an address. Then we work with you to make sure we catch him and he gets sentenced."
The detective nodded before leaving the room as Morgan called Garcia.
"Centre of awesomeness, you have reached your oracle of information who was beginning to feel forgotten about, how can we help you today?" answered Garcia in her usual upbeat tone. The three British teens all smirked slightly at the reference to an oracle, knowing that Garcia was in fact as close as the muggle world could get to having one.
Morgan passed on the parameters to Garcia and after a minute she came up with seven names.
"Why is it always seven?" questioned Hermione which resulted in a snort from Neville and Luna. The other occupants of the room looked slightly confused but ignored it nonetheless.
"Garcia, do any of the seven have the last name Black?" asked Spencer, hoping that his hunch based on the connection with Hermione would pay off.
"Three," Garcia's answer had him slightly disheartened until Hermione spoke up again.
"Of those three, how many only have a paper trail from the age of eleven?"
"Erm, that would be one, his name is Oscar T. Black and he lives and works at the congress hotel, built his way up from a bell boy to an assistant manager, he applied for the police three times, each time he was rejected after going through the psych eval, but the first time at the age of twenty one he only just made the fitness cut."
"Anagram," Reid pointed out, "when did he last apply for a job with the police?"
"Just before the killings started."
"Let's tell Detective Gordon and go," said Gideon.
