Carjackers doomed to die in petty theft gone horribly wrong

A few days ago, a truck carrying a container of radioactive cobalt-60 (enough to make a dirty bomb) was stolen by carjackers off a highway near Tijuana. Today, authorities found the truck. The thieves probably aren't terrorists, just some guys who wanted a truck with a crane attached to it. But, at some point, they opened the container of cobalt-60 and will now almost certainly die from radiation exposure.
