CSI: NY2004

Jo Danville:
Okay, I hope y'all are taking notes. First of all, I could not stop thinking about these two pieces of violet flavored gum, because I couldn't wrap my head around how they wound up in Jimmy Philbrook's mouth and on Greg Barbera's satchel. So I went back to the schedule from the courier service that Greg worked for, and it turns out that his first pickup of the day was across from a little diner in Chelsea, right around the corner from the Cragston Hotel.

Mac Taylor:
Who'd he pick up from?

Jo Danville:
Jimmy Philbrook. And guess what the diner has in a little dish next to the cash register?

Lindsay Monroe Messer:
Violet gum.

Jo Danville:
Bingo. But there was something else that kept bugging me, because Greg Barbera is a bike messenger, right? So why did he run from Scott Perfito? Where on earth was his bike? So I went back and I looked at the NYPD surveillance footage one more time. Look what I spotted about a hundred yards ahead of both of them.

Danny Messer:
Guy on a bike.

Jo Danville:
Yes, but not just any bike. It matches the exact description supplied to us from the courier service that Greg worked for. And look what's hanging from handlebars.

Don Flack:
A chainsaw. Could've been used to cut down the fallen tree outside of Scott Perfito's apartment.

Mac Taylor:
Where Greg probably locked up his bike.

Lindsay Monroe Messer:
Greg's bike was stolen, so he had to run away from Perfito on foot.

Sheldon Hawkes:
Which caused him to fall down the stairs.

Jo Danville:
And due to Greg's untimely death, he wasn't able to deliver this.

Mac Taylor:
Doug Kramer. That's the name of the Building and Safety official who was supposed to accept the bribe from Jimmy Philbrook.

Jo Danville:
For fifteen grand.

Don Flack:
But since he didn't get it, he ruled to condemn the Cragston Hotel at the B&S meeting.

Jo Danville:
Yes. Which we all know, drove our super, Toby Delafont, into a murderous rage.

Danny Messer:
He attacked Philbrook in the park, leaving him for dead.

Lindsay Monroe Messer:
Right, and then Philbrook wandered further into the woods, right into the path of Nicholas Bristow's arrow.

Don Flack:
That's the craziest thing I've ever heard, but it actually makes sense.

Mac Taylor:
One crime leads to another.

Sheldon Hawkes:
And another.

Danny Messer:
And another.

Lindsay Monroe Messer:
And another.

Jo Danville:
And that, ladies and gentlemen, is known as the ripple effect.
