As RadarOnline.com has previously reported,  Brown - whose marriage to his fourth wife was featured on Sunday's season finale of the brand new TLC reality show -  has been under investigation for the past several weeks.

Utah County Attorney Jeff Buhman confirmed to RadarOnline.com on October 6 that Lehi Police turned over the Brown case to them earlier that week.  At that time,  Buhman said authorities were  deciding if they would press charges.
