Peterson is sitting in jail because of the death of his third wife, Kathleen Savio. The grand jury that met about a half-block away from the jail is considering charges in the disappearance and potential death of Peterson's fourth wife, Stacey. And, Thursday, that grand jury heard from three potential witnesses.
Tom Morphey's wouldn't talk to reporters Thursday, but he did speak to the grand jury investigating the disappearance of Stacey Peterson. Morphey, who is Drew Peterson's stepbrother, has previously said he believes he may have helped Drew dispose of Stacey's body in a blue barrel.
Morphey talked to ABC's Chris Cuomo in March.
"He said, 'How much do you love me?'" Morphey told "Good Morning America" in March. "I said, 'I do.' And he said, 'Enough to kill for me?'"
Peterson's legal team points out trouble in Morphey's past that, they say, calls into question his credibility.
Also talking to the grand jury Thursday: two of Drew Peterson's former friends, Len Wawczak and his wife Paula Stark. For seven months after Stacey Peterson's disappearance, the couple secretly recorded their talks with the former Bolingbrook cop. But they have never publicly revealed the contents of those conversations.
"I know what we have. Drew knows what we have too," said Wawczak in July, 2008.
While Peterson was all smiles on his way in and out of court last week, he is anxious to get out of jail. Attorney Joel Brodsky has filed a motion asking a judge to dramatically lower Peterson's bond. It's now at $20 million. He would like to see it somewhere between $100,000 and $500,000.
On Monday, they may have luck getting that bond reduced, because in the more than year and a half that Drew Peterson knew he was a prime suspect, he never ran. He has family in the area, and if he were to flee, he wouldn't be able to collect his main source of income, his police pension.
