Nick and Boris planned a special prank for game night.  They hired an actor to rush into Nick's house, fire two blanks at Boris, who would fall over and pretend to die.  Nick would then draw a gun from a nearby drawer, shoot blanks at the intruder and give everybody a double scare.  But Nick placed real bullets in the gun he gave the actor, and in his own gun.  At midnight, the actor showed up and shot Boris.  As real blood spurted from Boris's chest, the stunned actor stood transfixed by the horrible sight. Nick then reached into the drawer, pulled out his gun and fired real bullets into the frightened actor.  An ambulance came for the mortally wounded victims, and Nick was charged with both murders.

Why did Nick put real bullets in the guns when it was supposed to be a practical joke?  Before clicking the answer below, can you answer the question?

The Kappa Delta fraternity of '55 had organized a tontine*.  Each frat brother contributed $100 to invest in stocks, with the agreement that all proceeds would go to the last member of the group. When Bill stayed overnight at the house of his old roommate Greg, the fund was well over $1,000,000, and they were among the three surviving members. Late that night, a car plummeted to the bottom of a ravine. The bodies of both Bill and Greg were found inside. Aside from being dead, Bill had a nasty bruise on his left temple.

It's 1948.  Ten years earlier, Brad's family had been massacred by Mac Shayne; In a nortorious case that came to be called the "Shayne Chain Saw Slayings."  After a long trial, Mac was convicted and sentenced to death.

The years Mac spent on death row took their toll in many ways: witness's memories faded, public sentiment ebbed, and evidence lost its potency.  Days before Mac was to die in the gas chamber, his third appeal, on the technical grounds, seemed likely to be granted.  Brad learned from a confidential informant in the Judicial Department the appeals court was moving toward reversing the conviction because of certain procedural errors during the trial.  In their reluctance to do so, they planned to wait until the last possible moment to call the prison with the order for a stay of execution.

Mac was to be sent to the gas chamber at midnight; Brad learned the call would come in at 11:55 PM. Vowing that justice would be served, Brad hatched a plan.  At 11:55 PM that night, the telephone line outside the prison was cut down.  With the pole down, the call to stop the execution couldn't go through.  Mac died right on time at midnight.  The police suspected Brad, and obtained a search warrant.  Based on two pieces of evidence found in Brad's basement, the officers arrested him for murder.

What were the two pieces of evidence?  How did Brad murder Mac?  Can figure it out before clicking on the answer below?
