GREG SANDERS: You got a hot dog?
CATHERINE: This one of your jokes, Greg?
GREG SANDERS: I got the ketchup.
CATHERINE: I’m sure this is meaningful.
GREG SANDERS: I went back and looked at the ejaculate from the last two
murders. The same thing. “Indeterminate red stuff.” It’s c12, h22 and o11, nacl, h2o and tomato paste.
CATHERINE: Sugar, water, salt and tomato paste. Ketchup?
GREG SANDERS: Ketchup.
CATHERINE: Well, does he add it after or is it organic?
GREG SANDERS: Don’t ask me why, but, uh … he adds it.
