In an exclusive interview with CBS News California, Huskins and Quinn detail what happened after the documentary ends. They knew Matthew Muller had committed additional crimes, but they say Vallejo police and the FBI refused to investigate.

Two weeks after he drugged and kidnapped Denise Huskins from her Vallejo, California home in 2015, "American Nightmare" kidnapper Matthew Muller allegedly committed another crime in neighboring Contra Costa County.

Kidnapping and rape survivor Denise Huskins spoke to reporters in Seaside on Tuesday about how she helped investigators find more victims who were allegedly targeted by Matthew Muller. The Muller case regained traction after it was detailed in a popular Netflix documentary,

Where is Matthew Miller, the subject of 'American Nightmare' who kidnappd Denise Huskins, now? What he had to say about his crime and the latest charges he is facing.

Years before Denise Huskins was kidnapped from her Vallejo home, held captive, and accused by police of carrying out a “Gone Girl” inspired hoax, Matthew Muller had other targets, investigators said.

Matthew Muller, already serving a 40-year sentence in the Denise Huskins case, had been terrorizing the community for two decades before the widely known "American Nightmare" case, prosecutors said.

In addition to the "American Nightmare" case and another home invasion, Matthew Muller is now linked to a 1993 kidnapping and sexual assault case, along with two home invasions in 2009 and a 2015 home invasion and kidnapping case.
