Who did it?

There was a theft at a nearby school. The school had a science fair a few months ago and one of the student projects was called, "solution X, A Cure For The Common Cold." It generated a lot of interest at the fair, at the end of the fair a parent even tried to steal it. The project was put in a school safe, but this morning the safe was found open, and the science fair project was missing. In it's place was a note written with a black tipped pen. The note said:
"You can catch a cold, but you can't catch me, I'll run like a nose unless I get a fee. Number 1 with six zeros after. Pardon while I launch into mechanical laughter. Bwa ha,ha, ha, ha, ha, ha, ha, ha"

Here are our suspects:

A. Kat Chacold: She works for a company that makes medicine. She states that she is not a common thief. She was however asking the student who did the project a lot of questions. What if she stole the recipe for her company? That would be worth a fortune!


B. Ed Chew This muscle bound home economics teacher is angry that they took away his electric mixers due to budget cuts. There's even a rumor he is giving steroids to the kids in his class to build up their muscles so they can make cakes that are light and fluffy. What if Ed Chew stole the project to sell, and make money to buy equipment for his class?
C. Ronnie Noze: he is the Principal of the school and coach of the local champion softball team, who always seem to have a runny nose. It is also true that Ronie Noze has the best pitcher on his team. She always has a cold but never misses a game. Some people wonder if her runny nose has something to do with why the balls she pitches are so hard to hit. Maybe Ronnie Nose stole the projects to prevent a cure for the common cold. Maybe he's afraid his pitcher wouldn't be as good if she didn't have a runny nose?
D. Ivana Tishu: A mother with a big family. She is dedicated to her children and professes not to steal. Her 6 kids are always sick and the family uses many tissues. They have had to buy larger garbage cans. She may be trying to save her family money by stealing the cure or save the landfills....
E. Noah Snotme: His daughter goes to the school that was robbed, but he doesn't work there or have anything to do with it. Noah was angry because his daughter's science project, "Cosmetics for Cats," was out shown by the "Solution X, the Cure for the Common Cold" project. He worked very hard on the project. Oh yeah, I think his daughter helped a little too. So perhaps he's angry about his daughter's project being rejected, and decided to get revenge by stealing the "Cure for the Common Cold" project.
F. Hannah Kercheef: She is a successful clothing designer. She had made a lot of money selling shirts she designed with super absorbent material on the sleeves. They are called "hanky sleeves" and they are for wiping your nose. Hmmmm. Maybe Ms. Kercheef is afraid that if the common cold is cured, she'll be out of business.
Luckily the cops were able to identify these suspects and found them all in possession of a black felt tipped marker. The same type used on the ransom note! We have the chromatography sample from the ransom note as well as the 6 markers that were confiscated from the suspects. We tested the pens...

After testing all of the pens we identified that the pen found with Noah Snotme had the same chromatography design as the ransom note.

Is this enough evidence to convict him?
Our defense lawyers deliberated over this one.

The bigger question to ask really is, why do some pigments creep up the chromatography paper higher than others????? Hummmmmm....
