A Camden County man who legally changed his name to Seven Moon was convicted Thursday of repeatedly assaulting two female relatives for years inside his Lindenwold home, which prosecutors called "a den of horrors."

Prosecutors said the abuse took place between 2007 and 2011 inside 51-year-old Moon's residence at the Arborwood Apartments, where the women "were kept with little exposure to the outside world and were routinely violated."

Moon, born Howard Gregory, was convicted of multiple instances of sexual assault against one of the women, who was a teenager when the assaults began.

Moon was also convicted of physically abusing another female relative in her early 30s. On one occasion, he restrained and beat the woman while threatening to kill her son.

The attacks eventually became so frequent and severe that the victims left the apartment and reported years of abuse to police, prosecutors said.

A jury found Moon guilty of four counts of second-degree sexual assault, along with first-degree kidnapping, aggravated assault, terroristic threats and weapons offenses.

He faces a mandatory minimum penalty of 15 to 30 years in prison on the kidnapping charge alone when he is sentenced Aug. 15.
