In 1999 he offered a job and a bondage relationship to Izabela Lewicka, a 21-year-old Polish immigrant living in Indiana.
When she moved to Kansas City, the still married Robinson gave her an engagement ring and brought her to the county registrar where they paid for a marriage license that was never picked up.
In 1979 Robinson finally completed probation; but in 1980 he was arrested again on multiple charges, including embezzlement and check forgery, for which he served 60 days in jail in 1982.
After his release he formed a bogus hydroponics business and swindled ,000 from a friend, to whom he promised a fast investment return so that he could pay for his dying wife's health care.
He promised Lisa a job in Chicago, an apartment, and daycare for her baby, and asked her to sign several sheets of blank stationery.
A few days later Robinson contacted his brother and sister-in-law, who had been unable to adopt a baby through traditional channels, and informed them that he knew of a baby whose mother had committed suicide.
Investigators fear that there might be other undiscovered victims as well, in both the two neighboring Kansas City's and elsewhere.
As of 2017, with eight murder convictions across both states, Robinson remains on death row in Kansas.
In 1994 the mother and daughter moved from Fullerton, California to Kansas City and immediately disappeared.
Robinson cashed Faith's pension checks for the next seven years.
Gradually, Robinson became well known in the increasingly popular BDSM online chat rooms.
Because he made contact with most of his post-1993 victims via on-line chat rooms, he is sometimes referred to as "the Internet's first serial killer".
In 1957 he became an Eagle Scout, and reportedly traveled to London with a group of Scouts who performed before Queen Elizabeth II.
