The 14-year-old is believed to have died at the hands of builder Arnis Zalkalns, who had served a prison sentence for murdering his wife in his native Latvia.
On the sixth day of the inquest at the Royal Courts of Justice in London, a jury of eight men and three women announced their "final conclusions" relating to Alice's death.
They found that her death was "consistent with compression asphyxia".
Alice disappeared from her home in Hanwell, Ealing, on August 28 2014.
Her body was found on September 30 after Scotland Yard conducted its biggest search since the July 7 bombings.
Zalkalns was found hanged in a park on October 4 and police said the 41-year-old would have been charged with Alice's murder had he been alive.
Last week the inquest heard that police were unaware Zalkalns had murdered his ex-wife in Latvia until weeks after Alice went missing.
And a Home Office witness also revealed that it "sometimes happens" that convicted murderers are allowed into the UK .
Alice's mum, Ros Hogkiss, began the inquest on June 27 by telling jurors she was "stunned" a convicted murderer had been allowed into the country.
