Police: Woman who held 4 in cellar may have preyed on dozens 
 
 The woman charged with keeping four adults with mental disabilities locked in a squalid Tacony basement while collecting their Social Security checks may have victimized dozens of others, police said Monday. 
 
 When Linda Ann Weston was arrested Sunday, she had identification records for as many as 50 people in her possession, including power of attorney paperwork, forms of identification, and Social Security numbers, according to Philadelphia Police Lt. Ray Evers. The documents suggest that Weston has been running a wide-ranging fraud operation, he said. 
 
 "She might have been doing this for years, probably since she got out of prison," Evers said. 
 
 Weston, 51, served eight years in prison for killing a 25-year-old man who starved to death in her North Philadelphia apartment in 1981. She was sentenced in 1985. 
 
 Also arrested Sunday were Weston's boyfriend, Thomas Gregory, 47, of North Philadelphia, and Eddie Wright, 49, who police said is homeless. They are charged with criminal conspiracy, aggravated assault, kidnapping, unlawful restraint, and related offenses. 
 
 Investigators said they expect more charges will be filed as they piece together a timeline of the operation, which took place over at least a year and in several states. Police also face the daunting task of locating the owners of the identification documents in Weston's possession. 
 
 It is not known how Weston got in contact with the victims, how she managed to start collecting their checks, or how long she had been holding them captive, Evers said. 
 
 "I think it'll be some time before this all comes out," he said. 
 
 In addition to the neglect and malnutrition the victims endured, police also were investigating any possible physical abuse. 
 
 The victims - three men and a woman ranging in age from 29 to 40 - are being treated for undernourishment at area facilities and are under close watch. 
 
 "You can't get any lower than how they preyed on these people," Evers said of Weston and her alleged accomplices. 
 
 Police were in the process of finding relatives and said Monday that two of the victims were from Philadelphia. The woman, identified by CBS3 as Tamara Breeden, was reported missing in 2005 by her family. CBS3 also identified one man as Derwin McLemire. 
 
 One of the men is believed to be from North Carolina and was also missing for some time, Evers said. 
 
 "The relatives are just falling down on the floor to hear that these people were found," Evers said. 
 
 Police also asked for the public's help in finding relatives of victim Herbert Knowles, 40. People in Norfolk, Va., saw his photograph in the media Monday and contacted police. 
 
 The group is believed to have come to Philadelphia within the last month from Palm Beach, Fla., where Weston has a home. Police believe they moved suddenly to avoid authorities there. Before that, authorities think, the group may have been in Texas. 
 
 Florida authorities have begun sending Philadelphia police fliers with names of missing persons, Evers said, and the FBI has been called in to assist with out-of-state aspects of the investigation. 
 
 "We have to trace the steps of this the entire way," said FBI Special Agent J.J. Klaver. "We have to determine exactly what happened. You've got a horrific crime here. You've got vulnerable people who were severely mistreated." 
 
 Arthur C. Evans, commissioner of Philadelphia's Department of Behavioral Health and Intellectual Disability Services, said city officials would not discuss the case until they had learned more about it. 
 
 "We don't know what happened in this particular case," Evans said. 
 
 He and Kathy Sykes, Philadelphia's director for intellectual disability services, said the city does intake work for people with such disabilities who apply for a state and federally funded waiver program that helps pay for residential and other services, including rehabilitation support and in-home help. About 3,000 people participate in the waiver program, and it has a waiting list of several thousand. Applicants must have an IQ of 70 or less, Evans said. An average IQ is 100. 
 
 Most people with intellectual disabilities also are eligible for Social Security disability payments. 
 
 The investigation began Saturday with the discovery of the adults trapped in a fetid subbasement police likened to a "dungeon" in a building at 4724 Longshore Ave., where Weston's son and daughter live. They have been cooperating with police and have not been charged. 
 
 Turgut Gozleveli, the building's landlord, told police tenants had started complaining of suspicious people coming and going in the building. 
 
 When Gozleveli searched the basement, he found a door leading to a 10-by-15-foot space with a dirt floor. Inside were makeshift beds with blankets, as well as two small dogs. When Gozleveli shone a flashlight over the blankets, he said Sunday, "People's faces just started coming up." 

 The woman accused of keeping four handicapped adults chained in a Philadelphia basement and stealing their Social Security checks may have done the same thing to victims in Florida, Virginia and Texas, Philadelphia police said today. 
 
 Lt. Roy Evers says a search of suspect Linda Ann Weston's personal belongings turned up documents belonging to 50 persons. The documents included drivers licenses, Social Security cards and even power of attorney forms filled out to allow Weston access to the victims' money. 
 
 Evers says police believe that Weston, 51, and her co-conspirators, Eddie Wright, 49, and Thomas Gregory, 47, were carrying out a "widespread fraud scheme," and that police are now trying to contact the persons who gave up those ID's. When asked if there was evidence that anyone else was currently being held captive, Evers said, "We don't think so, but we have to make sure everyone is safe." 
 
 Police are also checking McLean, Texas, because some of the documents they found indicated that previous victim's came from that area. Texas is also Wright's home state. Other addresses were being checked in West Palm Beach, Fla., and Norfolk, Va. 
 
 In 1981, Weston was convicted of starving a man to death in a closet of her Philadelphia home. 
 
 She was charged with beating the man with a hammer, tying him up in a closet with only three meals over the course of two months, and beating him with broomsticks, according to the Philadelphia Inquirer. When he died, his body was stuffed into a plastic bag and dumped it in an abandoned house, according to the newspaper. Weston served eight years in prison. 
 
 Weston, her boyfriend Wright, and Gregory are now charged with locking up four mentally handicapped individuals in the basement of an apartment building in Philadelphia. Police allege that the three trafficked the victims from Texas to Florida to Philadelphia, where they held them in Weston's daughter's apartment building. 
 
 The victims were discovered by the building's owner, who noticed an unusual amount of trash on the property and the locked basement door. He heard dogs barking behind the door, and when he opened it, discovered the chained individuals looking distressed, according to the Philadelphia police. 
 
 The victims are believed to have been in the 6 by 10 foot boiler room for about 10 days. The female captive had been reported missing since 2005. 
 
 Two adult children of Weston's who lived in the house were not arrested. 
 
 Weston, Wright and Gregory are charged with criminal conspiracy, aggravated assault, trespassing, kidnapping, simple assault, reckless endangerment of persons, unlawful restraint, and false imprisonment. 
 
 Police are still deciding whether the case will be turned over to federal authorities because of the multi-state criminal charges, according to a spokeswoman.

– The Philadelphia woman suspected of chaining four mentally challenged adults in a basement dungeon to steal their Social Security checks may have brutalized as many as 50 other victims in similar schemes, according to investigators. Linda Ann Weston had documents, including drivers licenses and signed power-of-attorney forms, linked to dozens of people from Florida, Virginia and Texas in her home, said police. Investigators believe Weston, her boyfriend and another man may have been involved in a "widespread fraud scheme," and police are now attempting to contact people named in the discovered documents, reports ABC News. "She might have been doing this for years, probably since she got out of prison," a police spokesman told the Philadelphia Inquirer, referring to Weston's conviction in 1981 for starving a man to death in her closet. "You can't get any lower than how they preyed on these people," he added. The FBI is joining the case to help ID other possible victims. Weston and the two men have been charged with criminal conspiracy, aggravated assault, kidnapping, and unlawful restraint. The Philly victims—three men and a woman ranging in age from 29-40—are being treated for malnutrition.
