Disturbing case as mother stabs her own toddler to death 'on the orders of Spongebob Squarepants'

A mother in the US who killed her three-year-old 'on orders from SpongeBob SquarePants' will spend the rest of her life in jail.

Justine M. Johnson, 23, was handed a life sentence without the possibility of parole after she stabbed Sutton Marie Mosser 17 times just two days after she celebrated her third birthday, the Daily Star reports.

Prosecutors said Johnson’s brother came across a bin bag with a child’s foot sticking out of it at Johnson's home in Oscoda Township, Michigan, in the early hours of September 17 and called the police.
