If it is murder-suicide, it would be my belief that it was unintentional. Something perhaps happened in a fit of anger. With all the other bizarre speculations out there...I will give one as well. Perhaps Honey was having an affair (it is not unusual for extra marital activities) and Barry found out and wanted her to end the affair. Honey was very good looking, youthful in her appearance, described as very outgoing and her husband worked long hours. Being a very social person, I would imagine she would have made many male friends of her own. And who exactly was the trainer who was trying to get into the house when TPS had the house surrounded?
