The Eagan Police Department is seeking assistance in locating a missing vulnerable adult. 20-year-old Alexander Robles went for a walk on Tuesday at around 3pm and hasn’t returned–which officials say is highly unusual for him. Alexander also takes daily medication to prevent a serious medical condition. He is five-foot-nine, weighs 150 pounds and has brown hair and eyes. He was wearing a grey sweatshirt, black jogging pants and tennis shoes. Anyone with information is urged to call 911.
