Isaac Perez Guberek Ravinovicz
Isaac Perez Guberek Ravinovicz was designated by U.S. Treasury under the Foreign Narcotics Kingpin Designation Act in July 2013. Treasury described him and his son Henry Guberek Grimberg as leaders of a Bogota-based network that laundered drug proceeds for trafficking organizations, naming Ayman Joumaa among its clients. The U.S. Attorney’s Office separately announced an indictment charging him in a drug-money-laundering conspiracy. Treasury later identified a Madrid-based cell operating under his direction. Those records establish sanctions, charges and attributed network roles; the cited releases do not establish a conviction.[1][2][3]
Role in the network
Treasury said Guberek Ravinovicz and Henry Guberek Grimberg used apparently legitimate Colombian textile firms and shell-company accounts in Panama to move proceeds back to Colombia. It described several trafficking clients, including Joumaa and Jose Evaristo Linares Castillo. The release assigned leadership to the father and son jointly; it did not publish a transaction ledger showing which principal handled each named client’s funds.[1]
Identity and company links
OFAC also listed the name Isaac Guberek Rabinovich. Its July 2013 entry linked him to companies including C.I. del Istmo, Induitex, Chaps Investment, Inversora Panacol, Orbital Horizons and G&G Internacional. These identifying links make the corporate network more specific, but the listing does not allocate individual transfers or profits among him, his relatives and those businesses.[4]
Other named relationships
Treasury’s 2013 action covered 31 individuals and entities in all and described hundreds of millions of dollars in drug money across the wider network. It named Jose Evaristo Linares Castillo as another client alongside Joumaa, preventing attribution of the aggregate figure to Joumaa alone. The same release named Henry’s brothers Felipe and Arieh among designated relatives, but did not assign them a Joumaa transaction.[1]
Legal record and attribution
DOJ announced a one-count indictment of Guberek Ravinovicz, Grimberg, Johanna Patricia Ceballos Bueno and Dilleman Hernando Solorzano-Lozano for conspiracy to launder proceeds of controlled-substance offenses. The announcement explicitly stated that an indictment was only an accusation and defendants were presumed innocent unless proved guilty. A sanctions designation and a criminal charge are separate legal events; this page does not infer an outcome from either.[2]
Madrid collections and settlement
Treasury’s October 2013 account described cash collected by Calle Quiros and Rodriguez Badillo in Madrid being sent to accounts controlled by Guberek Ravinovicz and used to pay traffickers in Colombia. This is a more specific alleged direction-and-disbursement relationship than the general list of international transit jurisdictions. It still does not identify a particular Madrid collection as Joumaa’s or publish the underlying account reconciliation.[3]
Later actions involving associates
OFAC removed Arieh Guberek Grimberg on 28 April 2015 and Felipe Guberek Grimberg on 29 September 2016. Rodriguez Badillo was removed in the latter action; Calle Quiros and four remaining Spanish-cell companies were removed on 14 June 2017. Those are outcomes for named associates and entities. They do not constitute a removal or criminal disposition for Isaac Perez Guberek Ravinovicz.[5][6][7]
Related network and scope
An October 2013 Treasury action described Luis Santiago Calle Quiros and Maria Paloma Rodriguez Badillo as operating a Madrid cash-collection cell under Guberek Ravinovicz’s direction. Treasury said Joumaa used the wider Guberek network and separately described Joumaa’s enterprise as having benefited Hezbollah. It did not state that Guberek Ravinovicz was a Hezbollah member or identify a Guberek-to-Hezbollah transfer.[1][3]
Related Peruvian finding
El Colombiano subsequently reported that a July 2018 Peruvian prosecutorial determination found insufficient evidence to support suspicion of drug-proceeds laundering involving Calle Quiros and no indications of a profit-generating predicate crime. That reported finding qualifies the account of the Madrid associate. It should not be presented as a decision on the separate United States indictment naming Isaac, Henry, Ceballos Bueno and Dilleman Hernando Solorzano-Lozano.[8][2]
Financial mechanism and individual scope
Noam Binstok, Orna Mizrahi and Esteban Klor’s May 2026 INSS analysis describes trade, exchange businesses and hawala offsets as complementary means of financial settlement. It provides context for the alleged relationship between accounts controlled by Guberek Ravinovicz and payouts to Colombian traffickers. The model does not identify an additional personal transfer, establish knowledge of a specific payment’s criminal source, or quantify a receipt by Hezbollah.[9]
