murio desangrado: he died from blood loss
(even better suggestion from comments: bled to death)
One I hope you never have to say, but a good rendition of this phrase that came up in testimony by a mother of one of the recent extrajudicial army executions in Colombia (a so-called "false positive") in this great short piece about the new US military bases in Colombia by Al-Jazeera. In related Colombia news I'm disgusted to report that 17 of the alleged perpetrators of these so-called false positives have just been set free, supposedly because the courts were slogged. If the Obama administration insists on continuing to send massive amounts of money to Colombia, how about using it to fund the courts instead of the military?
