PUTNAM COUNTY, Fla. -- Eyewitness News discovered that the Putnam County Sheriff's Office is investigating Ronald Cummings' girlfriend, who claimed that she was at home and sleeping when Haleigh Cummings was taken. But a tip puts the spotlight on the 17-year-old girlfriend.

The most recent information investigators got was that Ronald Cummings' girlfriend, Misty Croslin, may not have been home when Haleigh disappeared from her Satusum house early last week.

"Obviously that puts a spotlight on her now, if that's the case," said Captain Dick Schauland. "We have a team of detectives that are following up on this and yes they are questioning her about that."

In a news conference Wednesday (watch news conference), Schauland said the information is one of the 1,200 tips that investigators are looking into. He says he doesn't know if it panned out. He says detectives have interviewed family members and girlfriend Misty Croslin several times.

"We have received that tip and they are following up on it. As far as a conclusion on the follow up, I don't have that," said Schauland.

On CNN, Tuesday night, Haleighs paternal grandmother, Terese Neves, spoke out in support of the 17-year-old's story.

"I believe someone went into the house and took her. I believe they either know my grandchildren and my family or Haleigh's mother's family," said Neves.

Sheriff's deputies also said they have the pink shirt that Haleigh was thought to be wearing when she disappeared. Deputies wouldn't speculate or go into detail about where or when they found what could be key evidence in the case.

"What we now need people to focus on is this face because we do not know at this time what the clothing was at this point," said Dominick Pape of the Florida Department of Law Enforcement.

The massive search for Haleigh was scaled back this week. Deputies do not want to say too much in fear of jeopardizing the investigation, but confirmed they set up a road block this week and interviewed at least 300 neighbors in the area.

"We will take any lead, any place, anytime," said Pape. "We've got a life of a 5-year-old girl at stake."

Another prayer vigil was held Tuesday night, at the Dunns Creek Baptist Church in Putnam County.

Haleigh's father, Ronald Cummings and the little girl's mother, Crystal Sheffield sat side by side while the community came together to comfort them.

"I care for the people even though I don't know them," said one neighbor.

The sheriff's office will hold the next briefing Wednesday afternoon.
