A man wanted by Rochester police for confronting his ex-girlfriend and threatening her co-workers is in jail in Mankato after a chase Sunday night involving a state trooper. Authorities say the woman was in her car eating lunch when the 37-year-old suspect from Eyota began pounding on the window, yelling at her to get out. Two of the woman’s co-workers told the man to leave or they would call police. Police say the suspect then grabbed a handgun from his car and waved it around, threatening to “shoot this place up” and eventually drove away.
