A British judge castigated a mother for focusing on her boyfriend before her child's safety and sentenced her on Friday to at least five years in prison for her role in the toddler's death.
The woman, her boyfriend and their tenant were all convicted of causing or allowing the death of a child, her 17-month-old son, known as Baby P.
Her boyfriend will serve at least 12 years for his role in the child's death. He was also sentenced on Friday to at least 10 years for the rape of a 2-year-old girl.
The couple's tenant, 37-year-old Jason Owen, must serve at least three years.
The British public was outraged by the case of Baby P, whose full name is protected by a court order, though he has also come to be known in the media as Peter.
The cherubic blond toddler died in August 2007, despite being on an at-risk register for vulnerable children and having been seen at least 60 times by social workers, doctors and police officers.
By the time he died, Peter had suffered dozens of injuries, the most serious being a broken spinal cord.
"Any decent person who heard the catalog of medical conditions and non-accidental injuries, steadily mounting in seriousness, suffered by Peter ... Cannot fail to have been appalled," Judge Stephen Kramer said as he sentenced the trio.
