MILWAUKEE (AP) – Milwaukee police say they’ve arrested a suspect in a hit-and-run that left one person dead and another critically injured. Two pedestrians were crossing a south side street Saturday night when they were struck by a GMC conversion van. Thirty-nine-year-old Juan Zapata-Guerrero died of his injuries. A 42-year-old Milwaukee woman remains hospitalized.  Police said Monday the driver of the van, a 43-year-old man, has turned himself in.  The Milwaukee County district attorney is expected to review the case later this week.
