HARRISONVILLE, Mo. -- A man who solicited sadomasochistic sex over the Internet using the name ''slavemaster'' is considered the prime suspect in the deaths of five women whose bodies were found stuffed in barrels in Kansas and Missouri, authorities said.
Last week's arrest of John Edward Robinson Sr., 56, led police to two bodies found Saturday on his property in La Cygne, Kan. Three more bodies in 55-gallon drums were discovered Monday at a storage locker rented by Robinson about 30 miles away, in Raymore.
Autopsies showed the victims died of blunt trauma to the head, authorities said.
Investigators began draining a pond on Robinson's property Tuesday afternoon and were to resume today.
''I would be surprised if we found any more bodies,'' said Paul Morrison, the district attorney in Johnson County, Kan.
Robinson was not immediately charged in the women's deaths. He was being held on $5 million bond after being charged Monday with sexual assault on two women at hotels.
The two women told authorities they objected to him photographing them and said he brutalized them in a way that went beyond what they intended. One of the women had traveled from Texas to have a sexual encounter with Robinson in April.
At least some of the five victims are believed to be related to Robinson's alleged Internet relationships with women interested in sadomasochism. He was known to use the screen name ''slavemaster'' in his computer correspondence and sometimes called himself James Turner in person, Morrison said.
The prosecutor said he expected to file murder charges by week's end.
Robinson had not retained a lawyer as of Tuesday and was being represented by the Johnson County public defender's office, Morrison said.
During a news conference in Harrisonville with Cass County Prosecutor Chris Koster, Morrison said the case began three months ago as a missing persons investigation. It gained momentum after the two women came forward.
''We had been working on this case for several weeks when those victims came forward,'' Morrison said ''It helped us out a lot. Kind of manna from heaven.''
Robinson was arrested Friday at his home at a mobile home park in Olathe, Kan., managed by his wife. Morrison said dozens of photographs of women and computer equipment were confiscated.
Koster and Morrison refused comment Tuesday on Robinson's sexual relationships.
The bodies found near La Cygne appeared to have been in the barrels for several months, Morrison said. The bodies found in the 10-by-12 foot storage locker in Raymore had been there for months or years, Koster said. Luggage and other items were stacked on top of the barrels in the back of the locker.
One of the victims was Suzette Trouten, 28, formerly of Monroe County, Mich., The Kansas City Star reported today. Lee Shukait, her cousin, said Trouten moved to the Kansas City area to look for work but the family had not had contact with her since March.
Relatives said authorities told them Tuesday of her death.
