A mum and her partner who murdered her 15-year-old son after subjecting him to a campaign of torture have been jailed for life with a minimum term of 39 years each.
Agnieszka Kalinowska and her long-term partner Andrzej Latoszewski had beaten Sebastian Kalinowski with a bed slat, whipped with an extension cable and stabbed him with a needle.
He eventually died of an infection caused by "untreated complications of multiple rib fractures" at his home in Huddersfield, West Yorkshire in August last year.
