In October 2016, authorities announced they had uncovered a drug ring that used karaoke machines and other electronics to ship large amounts of cocaine to the Hudson Valley area. In one package, they found nearly 6 pounds of cocaine in a karaoke machine, according to an article in Hudson Valley One.

In Sauk County Circuit Court on Monday, Assistant District Attorney Sue Mueller said Castro and Martinez were part of a “drug delivery ring” that included long distances and drugs received by mail. She said the amount of drugs recovered from the home was “astonishing.”

Authorities have estimated the street value of the drugs seized at the Baraboo home was about $29,000.

Castro and Martinez are engaged, and have a 2-year-old child together. Both have ties to California, but have lived in the Baraboo area since at least 2015, attorneys said in court Monday.

Prosecutors say Castro has a criminal history that includes carrying a concealed weapon as a gang member and threatening school employees.

Sauk County prosecutors have charged him with possession of meth, coke, marijuana and drug paraphernalia. He also has been charged with possessing a firearm as a convicted felon, obstructing an officer and bail jumping.
