Accused Mass Slayer Confesses to Murders of Three More Men : Crime: Milwaukee police say Jeffrey L. Dahmer now admits 15 total killings. They plan a search for victims today.

MILWAUKEE —  Jeffrey L. Dahmer has confessed to killing three more men, bringing to 15 the number of slayings he has admitted, police said Monday.

Investigators said they have determined that three of the killings occurred at Dahmer’s grandmother’s home in West Allis, a Milwaukee suburb.

Police believe that Dahmer, in whose apartment 11 mutilated bodies were found last week, is responsible for at least 17 killings, including that of a hitchhiker in Ohio 13 years ago. Authorities planned to search for the Ohio victim today at a property formerly owned by Dahmer’s parents.

On Monday, police confirmed three new victims--two men killed at the grandmother’s home and a Milwaukee man whom relatives said disappeared last summer after going to a gay-pride parade in Chicago.

None of the three bodies has been found, police said.

Investigators also have determined that one man whose skull was found at Dahmer’s Milwaukee apartment July 22 was killed at the grandmother’s home, said Robert Due, West Allis’ deputy police chief.

Two of the newly disclosed victims were men whom Dahmer said he picked up in Milwaukee bars, brought to his grandmother’s house and killed, Due said. The first of those killings was in January of 1985 or 1986, the second two months later, Due said. He said Dahmer was unclear on the dates.

Due would not comment on whether the two were dismembered or had sex with Dahmer.

In the previously disclosed killings, court records say Dahmer has confessed that he lured men back to his apartment to take nude photos, drugged them, strangled them and dismembered their bodies. He said he took pictures of the victims in various stages of mutilation.

The third victim disclosed Monday was Edward W. Smith, 28, of Milwaukee, police said. Dahmer confessed to killing Smith and disposing of the remains, but no body has been recovered, Lt. David Kane said. Kane would not elaborate.

Henry Smith, the victim’s brother, told WITI-TV in Milwaukee that his brother was reported missing in June, 1990, after failing to return from a gay-pride parade in Chicago.

Due said police learned that three of the killings took place at Dahmer’s grandmother’s home, on a tree-lined street southwest of the city, during an interview Friday with Dahmer.

Police removed a sledgehammer, a hatchet, a sewer grate cover and containers from prescription pills from the grandmother’s house, Due said.
