Pouring molten pyrite?

The "Alice in Wonderland" episode of CSI on March 21, 2012 involved an incident where a victim died after having gold poured down his throat. Ted Danson did an XRF and determined that it was not gold, but rather pyrite.

But pyrite doesn't exactly melt, especially when sulfur activity is not fixed.

Ask Jeeves notes: Pyrite has no melting point but exhibits a peritectic decomposition point at 1016 Kelvin where it decomposes to FeS and sulfur.
