Authorities in Bucks County are reportedly looking at a man in custody on unrelated charges to see if he's connected to the disappearance of four young men. Cosmo DiNardo was arrested yesterday for allegedly possessing a 20-gauge shotgun and ammunition. The Bucks County "Courier Times" reports an affidavit shows DiNardo can't have a gun due to a history of mental illness, including an involuntary commitment. Authorities say DiNardo is not currently considered a suspect. However, a source told Philadelphia's NBC10 he may be connected to the disappearance of four young men who have gone missing over the last several days.
