Aug. 20, 2011— -- Josh Powell, the only person of interest in the disappearance of his wife, Susan Powell, today made a teary plea for his wife's family to leave him and the couple's young sons in peace.

After a shouting match between his father and his father in law at a Puyallup, Wash., remembrance rally for the young mother, who disappeared Dec. 6, 2009, while Josh Powell said he was camping with their two children, the man arrived on the scene and spoke to reporters from ABC affiliate KOMO-TV in Seattle.

"Putting this in my neighborhood is not appropriate," Powell said. "They're trying to push an agenda. ... I don't know what happened to her. There are 1,000 different theories that people need to consider in strong and serious ways."

Friends and family of Susan Powell were holding a rally, passing out flyers and asking passing drivers to honk their horns if they remembered the missing woman.

Steve Powell, Josh Powell's father, confronted Chuck Cox, Susan Powell's father, at the rally, calling him a "liar" and a "cyberbully," KOMO-TV reported.

"Their group has accused me of murdering my daughter-in-law," Steve Powell said.

Josh Powell, 34, has maintained that he and his sons were camping in the middle of a blizzard the night his wife went missing from their West Valley, Utah, home, and that Powell left on her own. He has described his wife to the Salt Lake City Tribune as "extremely unstable."

Josh Powell has since taken his kids to live with his father in Puyallup, the town where both he Susan Powell grew up.

Investigators have called Josh Powell a person of interest in the case.

"We're dealing with a lot of uncooperative behavior from Josh Powell," West Valley Police Sgt. Mike Powell told ABC affiliate KTVX in Salt Lake City Friday. "He has just not come forward, he's not cooperative with police. And as a result we are having to utilize these different aspects, such as information from search warrants to be able to obtain some of the investigative information we may or may not need."
