(AP Photo/Mexico's Attorney General's Office, File) (Newser) – Mexican officials are considering exhuming the remains of the parents of killed Los Zetas cartel boss Heriberto Lazcano. Mexico announced earlier this month that Lazcano had been shot down by Marines. But his body was spirited out of a funeral where it was being held, reports the BBC. Now officials want his parents' DNA to match it to samples taken from the body to convince the public that Lazcano is really, really dead.
