Roberto V. Arguelles (February 14, 1962 – November 15, 2003), known as The Salt Lake City Strangler, was an American serial killer and sex offender who, while serving a life term for child molestation, confessed to raping and killing at least one woman and three teenagers in West Valley City, Utah from February to March 1992. He later pleaded guilty and was sentenced to death for the murders, but died from natural causes at the Utah State Prison before the sentence could be carried out.
