CLEVELAND (AP) - Authorities say alleged serial killer Anthony Sowell is among a narrow subcategory of killers who hunt their victims from home.

The designation includes the 1893 Chicago Fair killer, Milwaukee cannibal Jeffrey Dahmer and John Wayne Gacy, who had 27 bodies
buried beneath his Chicago-area house.

National serial-killer expert Robert Keppel says such killers are so rare that it's impossible to understand why they took such actions.

Police say Sowell lured women into his home in a busy neighborhood, killed them and scattered their remains throughout the inside and buried some in the backyard.

His home and backyard - a burial site for five victims - were shielded by an empty home to the left and the windowless brick wall of a sausage company on the right.
