The four victims remain in a Wynnefield facility for the mentally challenged. The only woman in the group, 29-year-old Tamara Breeden, has told police she gave birth to two children during the course of being held inside the subbasement allegedly by Linda Winston and her two accomplices.
UPDATE: 10 more linked to dungeon victims, suspects
Meanwhile, officials continue to look into the connection between the disappearance of a teenage girl in Florida and this case.
15-year-old Benita Rodriguez had been missing in Florida since July 4th.
Just before 11:00 p.m. Monday, Action News was told by authorities that Rodriguez has been found in Philadelphia.
"I just want to hold her and love her," said Juana Rodriguez, the teen's mother. "I just want to hold her."
Authorities say Benita had been seen with the son of Gregory Thomas, one of the men arrested as part of the so-called "Tacony dungeon" case.
Her family says that bust may have led authorities to Benita.
"I can breathe, I can breathe. She's doing good, she's okay," Juana Rodriguez said.

The teen's discovery comes after a terrifying one over the weekend, when a landlord found four mentally handicapped adults held in a 10 by 6 room.
Heavy chains tethered one man to a massive, rusty boiler.
Investigators say this is where alleged ringleader Linda Weston, her boyfriend, Gregory Thomas and another man, Eddie Wright, would leave the victims at night with no light, little water, and a bucket to defecate in.

Police believe Weston, her alleged cohorts, and the victims arrived in Philadelphia a little over a week ago, but over the past few years they'd been living in Killeen, Texas and West Palm Beach, Florida.
Detectives believe Weston used the adults for the social security checks.
"There is some indication that, as law enforcement or human services or government agencies got close, they would change locations. This could, and did, keep going on for years," said Philadelphia Police Commissioner Charles Ramsey.
The FBI is launching a national investigation, fearing there could be more victims. A search of the upstairs apartment where Weston was staying turned up documents with least 50 pieces of identification belonging other people from several states, including social security numbers.
One of the victims, Herbert Knowles, is from Virginia. His family learned of his whereabouts after seeing news reports over the past two days.
"We just kept hoping nothing was wrong with him," said his niece, Tiffany Davis. "We just didn't know where to find him."
Weston, 51, was charged with kidnapping, false imprisonment and other offenses, with bail set at $2.5 million.
Weston was convicted of murder and voluntary manslaughter in the death of her sister's boyfriend. According to news accounts, Weston and her sister beat him and locked him in a closet because he refused to support the unborn child he had fathered. He died of starvation weeks later.
It was unclear from court records whether Weston served any prison time.
Thomas and Wright are also being held on $2.5 million bail following their arraignments Sunday.
