The Lady and the Genius.

I know how they are doing it!

Four days. It's been four days and another person from their group has died. And nothing has gotten easier on the group.
"What if this is just one big suicide pack." Rossi suggested.
"If it was a suicide pack why not do it at the school?" Morgan questioned
"Has your cousin gotten back to you?" Hotch asked
"Not yet. He is working a case as well so he probably isn't dealing with our case as well."
"Maybe call him." J suggested
"Yeah not gonna happen. He doesn't think I should work this case cause of them killing themselves even though he knows full well I never got that far." I stated before drawing on the notepad I had been given.
"Are you ok?" Emily asked
"Yeah I'm fine. He just makes me mad."
"What are you drawing il mio piccolo genio?"
"Random things."
"It helps her think of why this whole thing is familiar." Spencer told not removing his gaze from the board.
"I do it a lot at my shop when it's slow." I told before my phone began to ring.
'I'm gonna kill them.'
Before I could grab it Morgan pick it up and answered it making my eyes go wide.

"Hello?"

I didn't move as I waited for him to question everything.

"On no this is her number. I just picked her phone up. Yeah I can give it to her." He told before handing me the phone. "Some dude who says he knows your cousin."

I took the phone out of his grasp and placed it to my ear.

"River Finley here."
"Ah yes. You sound much younger then I thought you would."
"I'm 26 what are you 19?"
"Why do you both do that?"
"Do what?"
"Never mind. My name is Lance Sweets and I'm the Washington DC FBI Psychologist...."
"My cousin is seeing a shrink who's a child?"
"Ok I should have seen that. He mentioned your hate for psychologist."
"I hate people trying to make sure I don't end up like a killer cause of my past and ask me the same questions over and over again. I did psychology when I went to uni. So why are you calling me?"
"Well your cousin has his hands full at the mom...."
"IM HOLD A SKULL COVERED IN SLIME SWEETS!" He shouted making me move the phone away from my ear till he was done.
"Yeah I'm putting you on speaker." I told before doing that and placed it on the table. "So did you work anything out Sniper?"
"So I did some digging and discovered that the group you told me about had a kid who died before break happened."
"What happened to them?"
"Apparently he died of an allergic reaction to some type of medication."
"So I was correct they are being drugged. Noted."
"So what was he like as a child?"
"SWEETS!"
"What I wanna know."
"A prick."
"And I thought you got over hating me."
"Well you be wrong now don't ye."
"Anyway. It got me thinking, remember what happened when we were kids."
"Where I kicked your ass?"
"No."
"When you nearly punched a clown?"
"No."
"He actually shot a clown head."
"Sweets!"
"That makes sense why your seeing a shrink now. Was it an ice cream van again?"
"You've shot one before then?!"
"No Sweets."
"He punched one cause I threw it at him."
"River we've gotten distracted."
"Oh true."
"When Nik was having one of his bad episodes and since I had never seen it before you took me out of the house. And I said along the lines, it seemed like he became possessed all of a sudden before you told me what was going on."
"HOLY SHIT!"
"What?" They all asked at once.
"I gotta go Sniper. Have fun with the skull."
"See ya Brains."

I quickly hung the phone up and stood up as I began to pace back and forth to think.
"Are you ok Finley?" Hotch asked
"Shush."
"Did she just tell Hotch to shush?" Emily asked
"Shush."
"She also told Emily." Morgan told
"Shush!"
"When thinking she likes silence." Spencer told.
"People! SHUSH!"
They all fell silent as I continued to think.
"Let me think. Let me think. Ok you know what drug causes this effect you just need to remember. I know you know. What did she use? Horse tranquilliser! No she didn't like the effect it put him in. Think, think, think, think. Mental status changes in drugs that she used on him what is it?"
"River are you ok?" Rossi asked but I ignored him.
"I know the drug I just....I just gotta remember..... Parkinson's! That's right she had access to Parkinson's medication which is what she used! It's L-dopa! They are using L-dopa to drug the victims till they go crazy enough to kill themselves."
"You sure about this Finley?" Hotch asked
"100%, I know the effects it causes people who don't have parkinson disease to have. That is what they are using."
"How do you know the effect River?" Prentiss asked
"I can't say. You guys just have to trust me."
"River we aren't going to...."
"I know that. I just can't because I signed a contract stating I wouldn't tell anyone. So please, just trust me."
"Morgan..."
"On it." He told as he got his phone to call Penelope.
'Thats why it was similar.'
