The investigations published soon after the fact by Bellingcat, the New York Times, and [[Forensic Architecture]] were later confirmed by an in-depth report by James Harkin and Lauren Feeney in ''[[The Intercept]]''.<ref>{{cite book |last1=McMahon |first1=Félim |title=Investigative Journalism |date=2021 |publisher=Routledge |isbn=978-0-429-06028-1 |edition=3 |chapter=Digital sleuthing|pages=66–67}}</ref> After six months of examining the evidence, interviewing witnesses, and consulting with experts such as Higgins and [[Theodore Postol]] of the [[Massachusetts Institute of Technology]], James Harkin concludedand inFeeney ''[[The Intercept]]''concluded that Syrian Air Force helicopters dropped two chlorine canister bombs on Douma on 7 April 2018. Harkin noted that many chlorine attacks launched by Syrian forces in the past had resulted in no casualties, hypothesizing that—in contrast to the much more lethal sarin gas—Syrian forces likely employed chlorine at Douma to induce panic among the population rather than to kill many people. One of the canisters never released its payload and caused no deaths, but the other canister struck the weak roof of an apartment complex at an unexpected angle, releasing a very high concentration of chlorine that killed the people beneath it in a matter of minutes. According to Harkin, the frightened residents seen flocking to a nearby hospital and being doused with water in viral footage were not survivors of the chemical attack, but victims of conventional weapons and smoke inhalation.<ref>{{cite web|lastlast1=Harkin|firstfirst1=James|last2=Feeney|first2=Lauren|url=https://theintercept.com/2019/02/09/douma-chemical-attack-evidence-syria/|title=What Happened in Douma?
