Danai Muhammadi, 24, and Farhad Mahmud, 35, have been found guilty at Maidstone Crown Court of murdering three generations of the same family in an arson attack at their home in Chatham, Kent.
Danai Muhammadi sprayed petrol into the home of his estranged wife as she, her baby son and their family slept upstairs, sparking an inferno which blocked their only means of escape.
Muhammadi's girlfriend Emma Smith, 21, was cleared of three counts of murder and two of attempted murder, but found guilty of three counts of manslaughter.
