[6] Rasmussen lived in a number of states including Arizona, Colorado, California, Idaho, Virginia, Texas, Ohio, Oregon and Hawaii, finally settling in New Hampshire sometime in the late 1970s.

After an argument with her family, Honeychurch left with Rasmussen and her two daughters, six-year-old Marie Elizabeth Vaughn and one-year-old Sarah Lynn McWaters.

[4] On November 10, 1985, the bodies of Honeychurch and Vaughn were found in a barrel in Bear Brook State Park in Allenstown, New Hampshire.

While using the pseudonym Bob Evans, Rasmussen dated Denise Beaudin, who disappeared from Manchester after Thanksgiving 1981 with her six-month-old daughter.

[6] He was arrested in Cypress, California, in 1985 under the name "Curtis Kimball" for charges of driving under the influence and endangering the welfare of a child but failed to appear in court.

[10] Rasmussen resurfaced in December 1999 under the pseudonym "Larry Vanner" when California-based chemist Eunsoon Jun introduced him to her family.

[10] Jun disappeared the following June and her body was found buried in cat litter in their home after having died from blunt force trauma to the head.

[6] A fingerprint match had confirmed that along with Vanner, he had previously used the aliases Jenson and Kimball,[5] linking him to the child abandonment case.

[8] DNA evidence eventually found that Rasmussen was not Lisa's father, and the case spent years without any significant developments.

[11] San Bernardino detective Peter Headley was assigned to Lisa's case in 2013, by which time genealogy website databases had grown substantially.

[6] Aided by genetic genealogist Barbara Rae-Venter in 2015, Beaudin's daughter discovered her mother's identity and that the man she once thought had been her father was her kidnapper.

[12] On January 26, 2017, authorities publicly announced that "Bob Evans" was a suspect in the disappearance of Beaudin and the Bear Brook murders.

[13] Additionally, they announced that DNA confirmed that he was the father of the middle child found in Allenstown but that Evans was a pseudonym and his legal identity was not known.

[14] Denise Daneault, a 25-year-old woman who lived two blocks from the Rahn residence, and on the same street as Rasmussen, went missing from a bar in June 1980.

[9][14] Police and FBI agents conducted a search in Manchester after receiving an anonymous tip regarding Daneault in November 2017, after Rasmussen was announced as the Bear Brook killer.

[18] However, DNA from Lamotte's relatives later proved that she was one of the victims in the Redhead murders, a series of unsolved homicides across the U.S. which are unrelated to Rasmussen.

[8] San Joaquin County Assistant Sheriff John Huber speculated that Rasmussen may have been responsible for killing Amanda Schumann Deza.

[8] Having previously been an unidentified victim, known as the "San Joaquin Jane Doe"[8] and the "Lady in the Fridge", Deza was identified by Othram on February 23, 2023.
