The Hiller Family in Chicago

In 1910, Chicago was a big city with lots of people coming in from the countryside. The family that we're centering on is the Hiller family. They go to sleep one night at September 19, 1910, relatively cool evening. Their house is very, very dark and they often slept with a gas powered night light. At 2 a.m., their daughter's room has been burglarized by a man who shoots them both dead.
