A note that was found inside suspect Robert Card's home earlier is being described as a suicide note addressed to the suspect's son, law enforcement sources with knowledge of the investigation told @abc News.
It's now known Robert Card used to go to the bowling alley & bar he shot up yesterday w/ his former girlfriend, who was expected to be at the bar at a special event. His being fired from his job & breakup w/his girlfriend last summer are thought to be major contributing factors.
