Updated: As of Monday evening, he has been located and is on the way to the hospital. We know nothing more, but it's good news.
Original story: Mark Bartishell, aka Jon Barty, age 32, was last seen in Uptown Thursday night/Friday morning. He was involved in an auto accident at 4870 North Broadway (near the car wash) and walked away after talking to police. He hasn't been seen since. He didn't show up for a family obligation on Friday night, which is out of character for him.
Obviously his family and friends are worried sick. They've filed a mising persons report with the police and are flyering the neighborhood. If you know anything, please call 9-1-1 or 312-XXX-XXXX. [Number redacted after Mark was found.]
Here's Patch's article about him and the ongoing search.
