Stacy Peterson's father testified Thursday before the grand jury investigating his daughter's disappearance, saying investigators asked him general questions about his daughter's marriage to former Bolingbrook police sergeant Drew Peterson.

Anthony Cales, 53, of Downers Grove, said the grand jury also asked about his daughter's interactions with her family.

"They asked general questions about 'Did Stacy ever go anywhere without the kids?' She never left the kids, they were always with her," Cales said. "They asked did I know about any marital problems or upcoming divorce, which I didn't."

Peterson's neighbor James A. Mitchem, Jr., and his teenage son also testified, but declined to comment.

Cales said he spoke with his daughter every day up until her disappearance. Other friends of family of the missing mom have said Stacy Peterson was the glue that held her family together, organizing family get-togethers and keeping in touch with everyone.

"She called me every day," Cales said. "If she didn't get me on the phone she always left a voice message."

The last message Stacy Peterson left her father is on file with Illinois State Police. In the Oct. 17 message, a cheerful-sounding Peterson gave her father her new cell phone number and told him she loved him.

Stacy Peterson, the fourth wife of Drew Peterson, 54, disappeared Oct. 28 at age 23. Police have labeled the disappearance a "potential homicide" and named Drew Peterson a suspect in the case. Investigators also re-opened the investigation into the March 2004 drowning of Peterson's third wife Kathleen Savio. An independent pathologist for Will County ruled her death a homicide in February.

A special grand jury investigating both cases has been meeting each Thursday since November and is scheduled to continue through April. In a Jan. 24 statement from the Will County State's Attorney's office, authorities said the grand jury could be extended another six months, if necessary.

Peterson has denied any involvement in either case and has not been charged with a crime.

Cales said he and Peterson used to get along but the two have not spoken since Stacy Peterson went missing.

"We actually got along really well," Cales said. "We tried to do a lot of things together, family things."

But Peterson's recent behavior, including offering a $25,000 reward for Stacy Peterson's "safe return," have incensed Cales.

"I see him on TV and some of the things he says just burns me," Cales said.

Monday marked the six-month anniversary of Stacy Peterson's disappearance. While police, friends and family have spent that time chasing tips and searching for her, Cales said he has taken six months off work to look for his daughter.

"(We take it) day by day," Cales said. "Some days are better than others."
