In a recent photo of Patterson taken in prison, the twisted killer appears overtired and sick. A prison source revealed to RadarOnline.com that he has been distributing bizarre behavior and is now "considered a suicide risk."
"He has started to turn mute and not speak a word," the prison source added. "There have been no visits and he has declined phone calls from family."
The source said Jayme's kidnapper is also "refusing to sleep."
"There was an eerie moment of silence as if they were communicating through eye contact," the source continued.
