Sad deal when one has an alarm system an elects not to either use it or test it . A small little barking dog is a great backup and friend in cases like these we seem to see more of each and every day.
I'll stop the monday morning quarterback thing now...... People just need to be aware that safe and sound is not a gimme these days.
Stay Safe !
and a pair of 150 lb rotties is a great first line ;-)
