A woman's relatives forced her to drink urine, shocked her with a stun gun, and assaulted her with pliers over the course of three to six months, cops said.
On Monday, Township, N.J. residents Edward Jester, 26; Georgianna Jester, 51; Ellen Hairston, 34; and Paulette Hairston, 44, were charged with aggravated assault, criminal restraint and weapons offenses in connection with the alleged torture, according to the Burlington County Times.
"These people are real sickos," a source familiar with the investigation and the family told the paper.
The Daily Mail reports that authorities don't know what prompted the abuse of the 37-year-old victim whose name was not released. The victim had been living with the relatives for about two years.
Police began investigating on Sunday after the victim went to a local hospital and staff alerted authorities.
UPI reports that police are still determining whether other crimes were committed.
