Weston was portrayed as a queen bee of kidnapping, torture and brutality.
A victim described the Tacony basement where he and three other mentally challenged victims were held back in October.
31-year-old Edwin Sanabria says he spent 10 years as one of her captors, being moved with others from Philadelphia to Texas, Florida to Virginia, and back to Philadelphia.
He testified to witnessing endless beatings at the hands of Weston and her cohorts Gregory Thomas and Eddie Wright.
According to Sanabria, they were beaten with fists, bricks, and electrical cords.
In court the prosecution showed gruesome pictures of bedsores, bruises and cuts that could only have resulted from neglect and cruelty.
Investigators say Weston kidnapped disabled people so she could rip off their social security checks while keeping them imprisoned.
Relatives of Thomas, claim that Weston is a mastermind of control.
"They have to be punished for it but I think she is the ring leader out of everyone, "said Robin Anderson.
"This is nothing but a modern form of slavery and she's the ring leader of the whole thing, "said Robin Taylor.
The prosecution also hit the quartet with more charges today, including aggravated assault, terroristic threats and theft by deception.
