In Campeche, Mexico, in May, lovers Jose Agustin Noh and Ana Maria
Camara Suarez succumbed to carbon-monoxide poisoning as they slept
after having sex in a hearse; they'd left the engine running to
keep the air-conditioning on. And in April truck driver Ling
Yiu-hung's 1997 death was officially ruled carbon-monoxide poisoning
by a Hong Kong coroner; Ling had passed out and died after being
stuck for hours in a traffic jam. (Source: "News of the
