Josh Powell, The Man That Burned His Two Son's To Death Leave A Final Message To Family [Listen]

As investigators pore over the gutted Washington state home of Josh Powell for evidence explaining how and why he murdered his two sons and killed himself in a gas explosion, ABC News has exclusively obtained what is believed to be his final words to his loved ones.

Powell left a voicemail for his family just 20 minutes before attacking his two young boys Braden, 5, and Charles, 7, with a hatchet and igniting a gas leak that blew up his house on Sunday afternoon.

"I am not able to live without my sons, and I'm not able to go on anymore. I'm sorry to everyone I've hurt. Goodbye," the voicemail message said.

Many are now looking at the tumultuous relationship that Josh Powell had with his father Steven Powell, whose September arrest led to charges of 14 counts of voyeurism and one count of child pornography. The pornographic images were kept in the home the two men shared with Josh and Susan's boys – a fact which led to Josh Powell losing full custody of his sons.

The boys were ordered in a Washington court in September to remain in the custody of Susan Powell's parents Chuck and Judy Cox because they had been living in a dangerous home environment with sexually explicit material, and because of the possibility that Josh Powell participated in the voyeurism and child pornography charges against his father.

Steven Powell has now been named a person of interest in the disappearance of Susan Powell, according to Seattle's Q13 FOX News, which reports that he was not overly emotional when he heard the news of the explosion, and has been uncooperative with Pierce County deputies. He is currently on suicide watch.

John Hallewell, who was Josh Powell's best friend, says that Sunday's murder/suicide was likely not done as revenge against his missing wife because "all he ever thought about was himself."

"Josh has his problems, but he was trying to do what was right and start a family and do all those things … I think especially once Josh moved to live with his father, and he just got a hold of him, and basically he went downhill pretty fast from there," Hallewell told ABC News.

"I don't think it could have been for revenge," Hallewell added. "I think it was more a case where he thought he was in a corner and didn't have a way of keeping the kids, and thought if I can't have them nobody's going to. I don't think he even thinks enough about anyone else to do it for revenge."

Alina Powell, Josh Powell's sister, released a statement on Tuesday regarding her brother's death.

"Josh and his boys spent more than two years being crushed alive by hate, harassment, and abuse. None of us could have anticipated the devastating tragedy that took place Sunday, but what this unimaginable loss shows is that hate will never end well," Alina Powell said in the statement. "Hate kills."
