Sometimes burglary is a one time act, but some criminals will not quit when they find an easy mark. This burglar found an easy target and stuck with it. The criminal knows the layout of the house well and keeps coming back. The family did not have a home security system, so they did not know they were falling victim to the same burglar. With a home security system, you will know who is coming in and out of your home, so you will not fall victim to repeat offenders.
