A man who admitted killing his neighbor in a mobile home park outside Atlantic City faces up to 20 years in prison.

Harry Shuman pleaded guilty to aggravated manslaughter in state Superior Court Tuesday.

Shuman was arrested in February after police found 27-year-old Ralph Tozer fatally shot inside his mobile home in Egg Harbor Township.

Police had been checking on a report of a missing male at the Atlantic Gardens mobile home park.

Under terms of Shuman’s plea agreement, he must serve 85 percent of his sentence. He is scheduled to be sentenced in February.

Prosecutors didn’t say what led to the killing.
