#3112: Geology Murder

XKCD comic, described below.
Transcript

[There's a lab bench with a dead Cueball-like person lying on it, with a dagger sticking out of his back. Cueball is standing to the left of the table, Ponytail is standing to the right looking at the dead body. All three are wearing lab coats.]

Cueball: We found him lying unconformably on the lab bench. I wonder if the iron-rich intrusion in his back is related.

Ponytail: It could be clastic. Maybe a rift opened in his body, and the intrusive material later fell into the hole.

Title text:After determining that his body was full of pipes carrying iron-rich fluid, our current theory is that the dagger-shaped object precipitated within the wound.
