The list of John E. Robinson Sr.’s victims grew to eight Thursday with his guilty pleas to five murders in Missouri. Many of the women shared Robinson’s interest in sadomasochistic sex or accepted his offers of jobs, money and places to stay.

Three of the Missouri victims were found June 5, 2000, stuffed in 55-gallon barrels in a rented storage locker in Raytown, Mo. They were:

• Beverly Bonner, 49, of Cameron, Mo., who met Robinson in the early 1990s. He was serving a sentence for stealing at Western Missouri Correctional Facility, where she was a librarian and her then-husband was a prison doctor. Bonner developed a relationship with Robinson and moved to the Kansas City area, telling relatives she had a new job that involved world travel. Authorities believe she was killed in the spring of 1997.
• Sheila Faith, a 45-year-old widow, and her paraplegic daughter, Debbie, 16, from southern California. Surviving on $1,200 a month in Social Security benefits, they were living in Colorado when Sheila met Robinson through an advertisement. They moved to Kansas in 1994 and, authorities believe, were killed that summer; Robinson continued to pocket the Social Security checks until June 2000.

Two of the women whom Robinson on Thursday admitted killing in Missouri — although he had not been charged in their deaths — have never been found. They were:

• Paula Godfrey, 19, who was from Olathe, Kan. According to the evidence acknowledged by Robinson in court, he met Godfrey in 1984 and offered her a job as a trade-show assistant at a company he operated called Equi II. At some point in that year, Robinson went to a motel where Godfrey was living in Belton, Mo., and hit her in the head with a lamp as they argued about money he had loaned her.
• Catherine Clampitt, who was 27 when she moved from Texas to the Kansas City metropolitan area in 1987. According to the evidence acknowledged by Robinson in court, he offered Clampitt a job, which she never took, but they became friendly and she often borrowed small sums of money from him. Robinson fatally beat her in mid-1987 at a Belton apartment after she asked him for money.

Of the three women Robinson was convicted last year of killing in Kansas, two were found on June 3, 2000, stuffed in buried barrels on property he owned in Linn County. They were:

• Izabela Lewicka, 21, a Purdue University art student with an interest in sadomasochistic sex. She met Robinson through the Internet in 1997 and moved from Indiana to Kansas, telling friends she was to illustrate a sex manuscript that Robinson was putting together. He rented an apartment for her, and her family never saw her again.
• Suzette Trouten, 27, of Newport, Mich., who encountered Robinson via Internet sites related to sadomasochistic sex. She came to Kansas in February 2000 for what Robinson told her would be a $60,000-a-year job involving world travel. Friends last spoke to her on March 1, 2000; evidence at Robinson’s trial included an explicit videotape of one of their sexual encounters.

The third Kansas victim was never found. She was:

• Lisa Stasi, 19, who stayed at several places with her infant daughter after separating from her husband in the fall of 1984. She was introduced in January 1985 to Robinson, who represented himself as a helpful Johnson County businessman and put her in an Overland Park hotel. Her family last saw her on Jan. 9, 1985, with Robinson. Two days later, he turned the baby girl over to his brother and sister-in-law daughter, who adopted and raised her — legally, they believed.
