Bravo's 26-year-old "MasterChef" finalist, Joshua Marks, who suffered from bipolar disorder, was found dead by an unidentified woman on Friday evening in a Chicago alleyway with a gunshot wound to the head. Chicago PD rules out the incident as 'apparent suicide.'

Via TMZ:

Multiple sources involved with the investigation claims the victim is Josh Marks. We're told officers also recovered a nearby weapon ... and they're still on-scene investigating. 

If you can recall, 7-foot-2 Marks was arrested by U. of Chicago cops in July after allegedly punching an officer and trying to grab his gun. Three officers tried to subdue Marks with batons and pepper spray, but he broke free and took off running. 

It eventually took 5 officers to chase him down and handcuff him. Once in custody, cops claim Marks blamed Gordon Ramsay for his outburst, claiming the celeb chef had possessed him and turned him into God. There was no evidence of drug use. Months before the arrest, Marks released a video for the "Make a Sound Project" -- an organization dedicated to helping people struggling with suicidal thoughts -- revealing he suffered from bipolar disorder. Police believe Marks was in a manic state during the U. Chicago incident.
