A federal grand jury has indicted a Hollywood Hills man and two Panorama City residents on allegations they were part of a trafficking ring that purchased narcotics via the “darknet” and then shipped the drugs to buyers in the Philippines, New Zealand, Poland and other foreign destinations.

Prosecutors on Tuesday said three people were accused March 22 of conspiracy to distribute methamphetamine and other drug-related offenses in an eight-count indictment. A press release from the U.S. Attorney’s Office in Los Angeles said the defendants used cryptocurrency to purchase narcotics via the darknet, then distributed large volumes of illicit substances overseas. The darknet is a version of the internet that requires browsing software that makes users nearly impossible to track or identify.

Michael Alan Goldberg, 34, of Panorama City, is suspected of directing the conspiracy, and his wife, Panorama City resident Donnica Mae Rabulan, 31, is accused of sending packages of narcotics to international buyers, according to the release. It said prosecutors believe the third person named in the indictment, James Caleb Kueker, 41, of Hollywood Hills, collected tens of thousands of dollars in drug money on Goldberg’s behalf and owned properties where narcotics were allegedly produced.

The release said that in May, a security manager at a Van Nuys shipping company notified federal authorities after nearly 21 kilograms of illicit substances were found in seven parcels that had been destined for the Philippines. Contact information associated with the intercepted shipment was linked to Goldberg.

Prosecutors said further investigation led officials to obtain a warrant to search homes owned by Kueker in Hollywood Hills and Valley Village. There, authorities found suspected drug labs, more than $150,000 in cash and a loaded AK-47-style rifle during raids on March 11. Three other people living in the Hollywood Hills residence were also arrested and charged with possession with the intent to distribute a controlled substance.

Goldberg, Rabulan and Kueker were held in federal custody as of Tuesday. Rabulan was accused of four counts of distributing methamphetamine in addition to the conspiracy charges filed against all three defendants. Kuecker faces one count of possession with the intent to distribute ketamine and one count of possessing a firearm in furtherance of a drug trafficking crime, according to the release. Both were set to stand trial on June 4.

Goldberg faces one additional count of distributing methamphetamine, and was scheduled to appear for an arraignment hearing on April 8.
