Another Lacie Peterson?

I was just reading CNN and came across this very sad story. I hope they find her alive. I am thinking maybe the father's "estranged wife" could be the culprit??? I feel bad for the 2 year old who must have seen it all. He said his mother was "in the floor". Read full story below:

NORTH CANTON, Ohio (AP) -- A pregnant woman vanished last week, leaving her 2-year-old son home alone, with furniture in disarray and bleach poured on the floor.
Jessie Davis, 26, was last heard from when she spoke to her mother, Patricia Porter, by phone on Wednesday. Davis is nine months pregnant.
"There's no suspects at this time. We're interviewing a lot of people, but no suspects at this time," Capt. Gary Shankle of the Stark County sheriff's office said Monday on CBS News' "The Early Show."
"Everybody in the investigation so far has cooperated fully with us," he said. Among those cooperating was Canton Police patrolman Bobby Cutts Jr., the father of Davis' 2-year-old son, Blake, and of Davis' unborn baby, Shankle said. Cutts' estranged wife also has cooperated, Shankle said.
Porter said that when she didn't hear from her daughter all day Thursday, she went to check on her Friday morning at her home near North Canton and found Blake home alone with a dirty diaper. (Watch mother make plea for daughter's safe return )
"That was really out of character. The smell in the house was really overwhelming," Porter said Monday on "The Early Show."
She said the mattress in Davis' bedroom upstairs was partially off the bed, a night stand and lamp had been knocked over and bleach had been poured on the floor.
Blake was rambling and crying, and said "Mommy's in the rug," Porter said. There was no immediate explanation for his statement.
Neighbors reported they had not noticed anything suspicious, said Chief Deputy Rick Perez.
Authorities searched the area using dogs on Saturday, and on Sunday they were joined by of about 60 volunteers, including Cutts, Davis' relatives, friends and neighbors.
North Canton is south of Cleveland in northeastern Ohio. In 2000, in nearby Ravenna, a pregnant woman was killed and her baby was cut out by a woman who had claimed she was pregnant and took the victim's baby as her own. She killed herself five days later.
