A jury has retired to consider its verdicts in the trial of three people accused of murdering three generations of the same family in an arson attack at their home in Kent.
Danai Muhammadi, 24, was the "principal figure" behind the arson attack which killed his estranged wife Melissa Crook, 20, and their 15-month-old son Noah at Chatham Hill in Chatham, it is alleged
Mrs Crook's father, Mark Crook, 49, was left critically ill with severe burns in hospital in East Grinstead, West Sussex, he died six days later. The tragedy happened after petrol was squirted through the letterbox of the family home. Flames cut off any escape route for the family.
