On September 6, 1949, 28-year-old Howard Barton Unruh shot 13 people, in less than 12 minutes, on his block in East Camden, New Jersey. The shocking, true story of the first recorded mass-shooting in America has never been told, until now.

The sky was cloudless that morning, when 12-year-old Raymond Havens left his home on River Road. His grandmother had sent him to get a haircut at the barbershop across the street - where he was about to witness his neighbor, and friend, Howard, open fire on the customers inside.

Told through the eyes of the young boy who visited Howard regularly to listen to his war stories, and the mother trying to piece together the disturbing inner-workings of her son’s mind, Ellen Green uncovers the chilling true story of Howard Unruh - the quiet oddball who meticulously plotted his revenge on the neighbors who shunned him, and became one of America’s first mass killers.

With access to Howard’s diaries, newly released police reports, and psychiatric records, alongside interviews with surviving family members, and residents of East Camden, Murder in the Neighborhood will have listeners of In Cold Blood, If You Tell, and American Predator absolutely gripped.
