A Briton living in the United States who plotted to kidnap, kill and eat a child is due to be sentenced on Tuesday.
Portway pleaded guilty in May to solicitation to commit a crime of violence (kidnapping of a child) and distribution and possession of child pornography.
Under the terms of the plea agreement, the US district court in Worcester must sentence him to between 216 and 327 months in prison, before he is deported.
The US Attorney's Office for the District of Massachusetts has said that according to the agreed statement of facts, Portway engaged in numerous chats with many individuals about a mutual interest in abducting, raping, murdering and eating children.
Many of these conversations were accompanied by the trading of child pornography. These chats also included images of children known to them, accompanied by discussions of the desire to sexually abuse, murder and cannibalise them.
Portway solicited several people for their help in abducting a child, predominantly Michael Arnett, of Kansas.
Portway used Skype and other methods to communicate with Arnett, trading child pornography including images of injured, mutilated and dead children while chatting about the sexual abuse, rape, abduction, murder and cannibalism of children.
Over months, he repeatedly solicited Arnett to kidnap a child for him, with the intent that Portway would ultimately rape, kill and eat the child.
Portway and Arnett discussed different ways to kidnap children and the age range that Portway preferred. Portway was told that Arnett had experience with the abduction and sexual abuse of children.
