Kari Bales insists that the man she calls her best friend and a “big kid himself’’ who loves his own children, and could not have killed someone else’s.

“It’s unbelievable to me,’’ she said. “He loves children and would not do that. It’s heartbreaking. I can’t imagine losing my children, so my heart definitely goes out to them for losing all of their children.”

She has not discussed the allegations with her husband, saying she knew the phone conversation she had with him was monitored. She said Bales seemed confused on the phone about where he was and why he was there. “I don’t think I’ll have to ask him,’’ she said. “I think he’ll tell me what happened from his point of view.”
