Two masked men identified as William Medina, 24, of Reading, and Robert DeCarr, 18, of Muhlenberg Township, tried to rob Krick's Korner in Reading on Monday afternoon and were shot to death by a customer, police said.
The pair "chose this store as their prize for the day, and it didn't work out very well," Berks County District Attorney John Adams told reporters Monday night.
The gunman, a friend of the store owner, was leaving a nearby apartment building when he saw the holdup and decided to wait outside until the robbers left, Adams said. But they threatened him and he shot both men once in the chest, Adams said.
The shooter's name has not been released. Adams described him as a "concerned citizen" who had a weapon permit and was within his legal rights to fire, The Reading Eagle reported ( http://bit.ly/1anQJ6g).
"He told these individuals to stop, and 'I'm calling the police,' and that's when these individuals drew their guns, and there was a scuffle," Adams said. "He used deadly force before deadly force may have been used on him."
Alexander Garcia Bialek, 21, was identified as the planned getaway driver. He has been charged with second-degree murder, robbery and related counts.
Court records don't list an attorney for Bialek, who was taken into custody to await arraignment.
