And She's Gone Again! Ha-HA!

BOLINGBROOK - Just a week ago, Drew Peterson and his much-younger fiancee were all lovey-dovey on the pages of People magazine.

Then she walked out on him. Again.

Neighbors spotted 24-year-old Christina Raines packing up and leaving Peterson on Friday afternoon.

Before leaving, Raines shouted to Peterson, "I'll be back for the rest of my stuff some time," said Peterson's neighbor, Sharon Bychowski, who watched the move.

Peterson lent a hand to his lady love as she moved out, Bychowski said, and the young woman's sister was also there.

When the two women departed, "Her sister whipped around the court (in her car)," Bychowski said. "'Agitated' is the word."

Raines, a single mother of two small children, took her kids to live with Peterson, 55, in January.

Not long after, Raines father, Ernie Raines, appeared on the "Dr. Phil" show to complain about his daughter's relationship with Peterson, whose third wife was killed and fourth wife disappeared.

In the wake of her father's TV appearance, Raines walked out on Peterson. A camera crew accompanied her father to record the break-up.

Then, in February, Raines and her children went back. But the romance apparently could not survive.

Peterson seemed to blame the press for this.

"Just the way you treated her in the media," Peterson griped. "It was out of line."

State police are investigating Peterson's possible role in the disappearance of his fourth wife, Stacy Peterson. They consider the case a "potential homicide" and have named Drew Peterson their sole suspect.

The state police also are looking into the March 2004 apparent bathtub drowning of Peterson's third wife, Kathleen Savio.

At the time, state police found no sign of foul play and Savio's death was ruled accidental. But after Stacy vanished, Savio's death was reclassified as homicide, and the state police got another crack at figuring out who killed her.

Raines, who joked about Savio's death on a radio show, has not seemed troubled by the fate of Peterson's last two wives.

Paula Stark, who says she wore a wire at the behest of the state police to record Peterson in 2007 and 2008, was also around Peterson's home Friday afternoon and said she watched Raines pack and leave.

Bychowski and Stark said they did not see Raines' children when she moved out. Besides mixing their families - Peterson's four youngest children still live with him - the couple also picked up a small dog.

Raines apparently did not want to take along the dog, Missy, when she left.

"The poor little dog was left behind," Bychowski said.
