A gun found on board a yacht along with $48 million worth of cocaine was kitted out with magazines that doubled its firepower, a jury heard.Latvian sailor Janis Zegelis is on trial at Supreme Court accused of importing and possessing the drugs and weapon, along with 192 rounds of ammunition.Prosecutors say Mr Zegelis, 28, was en route from the Caribbean to his home country in Eastern Europe when he was forced to divert his yacht Arturus to Bermuda for repairs.He arrived on July 21 and was arrested after police and customs officers raided the vessel on August 1 when it was moored at Captain Smokes Marina, near Tiger Bay, St George’s.Police gun expert Stuart Kirkpatrick examined the 9mm Beretta semi-automatic pistol found on the yacht. He described it as in good condition and fully functioning. It was found along with two extended magazines that could hold extra bullets, and which were loaded with 54 of them.“This increases the firepower of the weapon, doubles the ammunition you can put into the weapon and saves reloading,” explained Pc Kirkpatrick.In his opening speech on Monday, prosecutor Rory Field said: “Mr Zegelis had something worth $48 million in the front of his boat, and that’s a fortune in any country and enough to tempt any criminal to come to take it whether it’s overseas or on land. That’s why he had the weapon; to use it if anyone wanted to take the drugs.”He also remarked: “One can only imagine what could have occurred if criminals in Bermuda got wind of those drugs.”The jury also heard yesterday from firearms examiner Dennis McGuire who test-fired some bullets from the gun. He then examined the spent cases to see if they could be matched to bullets from open criminal cases in Bermuda. No such links were found, according to Mr McGuire.The jury also heard from Customs officer Addison Tucker who was present when the yacht was raided.“I asked Mr Zegelis what his occupation was and he stated that he held the rank of a second class mate for commercial ships,” said Mr Tucker.He confirmed that would make the defendant a qualified seaman.“I asked him about the ownership of the vessel. He replied he had owned it for two years and purchased the vessel.”According to Mr Tucker, when quizzed about his journey, Mr Zegelis said he had been in St Lucia for about six months, then in the Dominican Republic to visit his mother who lived there, then in Trinidad.The sailor said he had not planned to visit Bermuda but ran into bad weather 300 miles off the Island which caused damage to his yacht, so he had to get repairs.According to the customs officer, Mr Zegelis said he did not know anyone in Bermuda.Government analyst Desiree Spriggs told the jury she examined the drugs seized from the yacht, which consisted of 165 packages of cocaine powder and one package of cocaine pellets. The powder weighed 164 kilograms and was 81 percent average purity. The pellets weighed 952 grams and were 73 percent average purity.Mr Zegelis denies the charges against him, and the case continues.
