Recall, June 30 from his home in Amesbury was hospitalized a couple - 45-year-old Charlie Rowley and 44-year-old don Sturgess.
Police started a murder investigation after Ms Sturgess's death and are now said to be closing in on the people who carried out the attack. Sturgess died in hospital on July 8, while Rowley, who had been in critical condition, regained consciousness and was questioned by the police.
The suspects were identified by United Kingdom police, who have been combing through months of surveillance camera footage from United Kingdom airports and from Salisbury, the town where the Skripals were poisoned on March 4.
Investigators later confirmed that it was "highly likely" that the Novichok that Sturgess and Rowley came into contact with was from the same batch that had been used in an attempted assassination on former Russian double agent Sergei Skripal four months earlier.
They said on Saturday "a significant number (of the 400-odd items recovered) are potentially contaminated" and they have been submitted to laboratories for analysis.
British officials declined to comment.
The Press Association news agency reported that Russians were behind the attack. Ben Wallace, a security minister in the British government, described the reports as "ill-informed and wild speculation". They were treated for exposure to the rare Soviet-era military-grade nerve agent Novichok and discharged separately from hospital several weeks later.
Donald Trump should bring up the death of Dawn Sturgess when he meets Vladimir Putin, her grieving son has said.
The U.K. has blamed Russian Federation for the attack, a charge that the Kremlin has strongly denied.
Britain and its allies blamed Russia for the attack in March on the Skripals, prompting the biggest Western expulsion of Russian diplomats since the Cold War. British police are working under the theory that the cases are linked.
The attack on the Skripals plunged relations between Russian Federation and Britain to a new low, and sparked a wider diplomatic crisis that saw Russian Federation and Britain's Western allies expelling hundreds of diplomats.
Experts from the Organisation for the Prohibition of Chemical Weapons have been requested to assist in the investigation.
