Mario Angel Del Rio Sanz was one of seven foreign specialists who admitted joining a conspiracy to take possession of a vast cocaine shipment off West Cork. The specially adapted boat never met the merchant ship, but the Special Criminal Court found the planning, reconnaissance and logistics serious enough to start from an 18-year headline term. Del Rio Sanz received 11 years.

A transnational plan built around the Cork coast

The conspiracy ran between 27 February and 14 March 2024. Gardaí found reconnaissance material, pier coordinates, rental and transport arrangements, communications equipment and a rigid-hulled inflatable boat fitted with three 300-horsepower engines. Parts of the vessel were painted black and it carried minimal lighting. A former naval officer described its design as intended to detect without being detected.

The boat travelled approximately 985 kilometres while trying to meet the Panama-flagged Cool Explorer. Five crew members spent close to 48 hours at sea in rough conditions but failed to make the rendezvous. Days later, 840kg of cocaine valued at more than €58 million washed ashore near Jutland, Denmark; tracking and phone evidence connected the shipment route to the failed operation.

Del Rio Sanz’s proved role

Del Rio Sanz was a Spanish national and one of the men who remained on land during the attempted transfer. The sentencing evidence described the Spanish participants generally as hired specialists. His counsel put to the investigating inspector, who agreed, that Del Rio Sanz had been offered €15,000 to work in the trafficking operation.

He pleaded guilty to conspiracy to take possession of controlled drugs for sale or supply. This file does not claim he owned the cocaine, led the multinational network or personally crewed the sea mission. It records the land-based role and fee presented in his own sentencing hearing.

Eleven years at the Special Criminal Court

On 11 December 2025, the three-judge Special Criminal Court set an 18-year headline term for each conspirator before reducing it for the guilty pleas and individual mitigation. Del Rio Sanz received 11 years’ imprisonment. Ms Justice Karen O’Connor described the plan as audacious and brazen and said the conspirators had underestimated both the local community and law enforcement.

Two co-defendants received the same 11-year term, while the remaining sentences ranged from eight to ten years. Those comparator outcomes show the court assessed individual roles, but they do not turn the combined 70-year total into a sentence served by Del Rio Sanz.

Chronology

  • 22 February 2024: a roadside checkpoint search uncovers pier coordinates and accommodation details, helping trigger the surveillance operation.
  • 27 February–14 March 2024: the admitted conspiracy period.
  • 12–14 March 2024: the RHIB attempts to intercept the Cool Explorer but turns back to Cork.
  • 14 March 2024: Gardaí arrest participants and seize the boat, vehicles and equipment.
  • 17 March 2024: 840kg of cocaine washes ashore in Denmark.
  • 2025: Del Rio Sanz pleads guilty; detailed sentencing evidence is heard in July.
  • 11 December 2025: the Special Criminal Court imposes 11 years.

Public-cost boundary

At the Irish Prison Service’s 2024 average of €99,072 per available staffed prison space, 11 years produces a nominal face-value capacity benchmark of €1,089,792.

This is not an invoice or audited marginal cost. It assumes the full headline sentence at one annual rate and does not account for remand credit, remission, an actual release date or changes in annual cost. Garda surveillance, maritime and international coordination, prosecution, court and legal-aid costs are not quantified. The €58 million figure is an estimated illicit-market value, not a direct State expenditure or recovered public money, and is not added to the custody benchmark.

Accountability questions

  1. What was the full Irish cost of the prolonged surveillance, maritime response, international evidence work and Special Criminal Court proceeding?
  2. Were confiscation orders made against Del Rio Sanz or any fee due to him?
  3. What border, marina or commercial-vessel intelligence changes followed the operation?
  4. What is the final status of the seized RHIB, vehicles and specialist equipment?

Name and status limits

The court reports use Mario Angel Del Rio Sanz; Spanish sources may render the given name and particles with accents or different capitalisation. He is reported as a Spanish national with no fixed Irish address. The reviewed sources do not establish an asylum claim, unlawful pre-offence residence, a deportation order, a completed removal, a transfer or a present location. Nothing beyond the reported nationality and adjudicated conspiracy is inferred.
