Randy Roth is a convicted murderer and thief from Washington.  He was convicted of the 1991 murder of his fourth wife, Cynthia Baumgartner Roth.  He was suspected but never tried for murdering his second wife, Janis Roth, in 1981.

He was also convicted of stealing in the form of defrauding insurers and the Social Security Administration and was sentenced to one year for theft and 50 years for first degree murder in 1992.  At least two true crime books are based on Roth's crimes, "A Rose for Her Grave" by Ann Rule and "Fatal Charm" by Carlton Smith.
