A Mankato woman charged in the murder of her 17-month-old son has been sentenced.

28-year-old Chelsea Rae Olinger is sentenced to 7.5 years in prison

Court records say Olinger was arrested in February 2020 after she brought her child to the hospital in Mankato.

The toddler was then transferred to Rochester with a brain injury and several other severe injuries.

The boy died two days later. Medical examiners ruled his death a homicide.

Court records say Olinger claimed her son had fallen down a flight of stairs, but doctors at the Mayo Clinic said the injuries were not consistent with a fall, and appeared to be intentional trauma.
