David Dearlove, 71, murdered 19-month-old Paul Booth at their home in Stockton-on-Tees in October 1968.
Home Office pathologist Mark Egan demonstrated how the toddler could have died by swinging a doll by the ankles and banging its head on the surface of the witness box, causing some of the 10 men and two women of the jury to weep.
In a statement after the verdict, the Booth family said Dearlove's actions "not only physically killed Paul but also destroyed his memory".
"He was buried into an unmarked grave the location of which remains unknown and he was not spoken about for many years."

Paul's brother Peter, who was three years old when he witnessed the attack after he crept downstairs for a drink, went to police in 2015.
