BOLINGBROOK, Ill. -- A planned exhumation is the latest twist in a story that's developed since Sgt. Drew Peterson's wife, Stacy Peterson, disappeared last month.

Family members of Kathleen Savio, Peterson's third wife, say authorities have told them they're going to exhume the woman's body. Savio died in 2004. Melissa Marie Doman, Savio's niece, said family members support the decision by the Will County State's Attorney's Office. The family has said that they've long suspected that Savio didn't drown accidentally in her bath tub as was determined by the coroner's office.

They've planned a press conference for Friday afternoon to discuss recent developments in the investigation of their loved one's death.

As new information is surfacing about his previous wife's death, Drew Peterson on Thursday night broke his silence and spoke to reporters.

A neighbor who was with Drew Peterson when he found his third wife dead in a bathtub spoke to NBC5 on Thursday, saying that finding the body would be forever fused into his memory.

"It's something you'd see in a movie; it was something I'll never forget," said Steve Carcerano, who was Peterson's neighbor when he was married to Kathleen Savio.

Carcerano described Peterson's reaction when he saw Savio's body in the tub.

"He ran upstairs and upon seeing her, he just broke down and started screaming, 'Oh my God, oh my God! What am I gonna tell my kids?'" he said.

On Thursday, Peterson broke his silence with the media in front of his Bolingbrook home when he told reporters, "The media is terrorizing my children."

NBC5's Kim Vatis said that authorities are considering exhuming Savio's body for further investigation, after the Will County coroner cast doubt on the original findings of the 2004 autopsy results, saying that the death by "drowning" determination was inaccurate and that the autopsy results are, at least, "undetermined."

"Do you want to comment on the coroner's statement?" a reporter asked Peterson as he was going from his SUV to his front door Thursday night.

"I have no comments for the media because they did everything wrong," he said, barely showing his face under a hooded sweatshirt.

Vatis said that Savio's sister has come forward with more background on the couple's marriage. While they had gotten a divorce, she said, the finances were left uncertain and that Savio feared Peterson.

She testified that Savio once told her that if she should die, "it may look like an accident, but it isn't."

On Thursday night, Peterson would not confirm whether he had made any statements to the grand jury earlier this week, but instead voiced clear frustration with media coverage of his current wife's disappearance.

"What do you get when you cross the media with a pig," he asked reporters gathered outside his home. "You get nothing, because there are some things a pig wouldn't do."

State police investigating Stacy Peterson's disappearance are still saying that Drew Peterson is not a suspect.
