MEXICO CITY: Three Mexican soldiers accused of taking part in a massacre of 22 gang suspects in 2014 have been freed by a judge for lack of evidence, officials said, drawing dismay from human rights groups. The soldiers — the last of seven initially charged — were accused of killing eight of the suspected gang members in cold blood in a warehouse in the central municipality of Tlatlaya on June 30, 2014. The army initially said the 22 suspects were killed in a shootout. But a woman who survived said many of those killed, including her 15-year-old daughter, were executed by the soldiers after surrendering. Four of the arrested sol y been released last October for lack of evidence.
