Mexican officials announced yesterday the detention of Felipe Rodríguez Salgado, who they allege is the leader of the criminal group that killed 43 students and burned their bodies three months ago, the New York Times reports.

Human remains recovered by investigators in Mexico are believed to belong to 43 college students who went missing in September, reports the Los Angeles Times. The students were last seen being led away by police, who officials then believe turned them over to a gang to be killed.
