Fond du Lac, WI (WHBL-KFIZ) - The 45-year-old Ripon man who hid his brother’s corpse in a 50 gallon barrel is back in Fond du Lac County Court for a preliminary hearing today. Robert Diamentis allegedly hid his brother Richard’s body in a barrel after he died last February. Richard suffered from a medical condition that affected mobility and coordination and was bed ridden. Robert Diamentis told investigators he didn’t report his brother’s death because he feared people would accuse him of mistreating Richard.
