[Doctor Raoul]

Crappy reporting (no pun intended). No mention of the weather, cold or warm, no mention of what else was found in the room. No mention of how the bodies arranged.

All things you'd ask about to determine if this was suicide, an accident due to improvising heat or an accident from using a grill indoors.

an accident due to improvising heat or an accident from using a grill indoors.

This is a fairly common cause of death of Hispanics in Southern California (improvised, cheap heating). I'm sure it's not much different up in Starbucks country.
