Youshock was found guilty of attempting to murder his former chemistry teacher, Meghan Spalding; of exploding a destructive device in an act of terrorism; possession of a destructive device in a public place; carrying a concealed dagger; and carrying a concealed explosive.
The jury of six men and six women remained deadlocked on two remaining charges: that Youshock attempted to murder campus security guard Jana Torres when he threw a homemade pipe bomb as she advanced on him in the hallway at Hillsdale High, and the charge that he detonated that pipe bomb with the intent to kill.
Judge Stephen Hall asked the jury foreman if further argument by defense attorney Jonathan McDougall and Chief Deputy District Attorney Karen Guidotti would be helpful to the jurors in reaching a unanimous decision on the remaining two charges.
The foreman said further argument might be helpful, and the jury then met to formulate a potential focus for further argument.
Hall will announce his decision at 1:30 p.m. on whether he will call for a reopening of attorney statements.
