An Anchorage man has been sentenced to more than 13 years in prison for conspiracy to distribute heroin.
   
The U.S. attorney's office says Brackston Moores conspired with three others to distribute what he believed to be heroin but what turned out be a synthetic form of heroin.
   
The office says the man who manufactured the substance, Ryan Travis Brown of Florida was sentenced earlier this year to 12 years in prison.
   
The office says that U.S. District Court Judge Ralph Beistline cited Moores' criminal history and the seriousness of the crime as the reasons for handing down a 160-month sentence.
