 A high-ranking gang member has pleaded guilty to murder charges in New York. Alexei Saenz is a leader of the MS-13 gang on New York's Long Island. He's now pleaded guilty to racketeering and firearms charges in a case involving eight murders. In one case, prosecutors say the 29-year-old and his brother hunted two teenage girls down in 2016 and attacked them with machetes and beat them with baseball bats. CBS's Matt Piper tells us he faces up to 70 years in prison when he's sentenced in January.
