There is a lesson here: No Good Deed Goes Unpunished. This isn't the first time I have heard a story about someone responding to a neighbor's burglar alarm only to get caught up in the "incident" and wind up dead. It is called "Getting Caught in the Crossfire", IMHO, NOT A GOOD THING. The alarm system went off FOR A REASON, THE REASON is someone(s) broke into the house. The lesson? If you ever hear an alarm go off, dial 911 and STAY IN YOUR HOME until the smoke clears.
