Details of Disappearance

Roberts was reported missing from Anchorage, Alaska on March 4, 2008. Five years earlier, she had been arrested for felony drug possession, and her marriage ended in 2004. That same year, she was listed as a witness in the criminal case against Josef F. Boehm. He was a prominent Alaskan businessman who, over a two-year period, lured girls as young as thirteen to his home and exchanged drugs or cash for sexual services from them for himself and other men.

Boehm eventually pleaded guilty to drug offenses and sex trafficking and was sentenced to thirteen years in prison. He died in 2014. Roberts had evidently been considered an important witness in the case; Boehm allegedly asked Don Arthur Webster Jr., also known as Jerry Starr, to keep her at his condo so she could not testify against him. Webster, a pimp with a violent reputation who exploited young girls and got them addicted to drugs so he could control them more easily, was arrested for sex trafficking in 2006. In late February 2008, he was found guilty of 28 counts and sentenced to 30 years in prison. Photos of him and Boehm are posted below this case summary. Robert disappeared less than two weeks after he was convicted.

Although Roberts's date of disappearance is given as March 4, 2008, records show she had contact with police in Alaska three times after that date: she was arrested for prostitution on June 12 and July 30, 2008, and ticketed for a seatbelt violation on December 4, 2008. There has been no sign of her since then and the circumstances of her disappearance are unclear.
