TULSA, Okla. (AP) -- A Jennings man has been sentenced to life in prison without parole for the death of his girlfriend's 10-month-old daughter.

Online court records show 23-year-old Brandon Wade Nordstedt was formally sentenced Monday in Tulsa County District Court after being convicted Sept. 19 of child abuse murder in the July 2015 death of Emmerson O'Rourke.

Prosecutors say the girl died at a Tulsa hospital of brain injuries that the state medical examiner determined were caused by blunt force trauma.

Nordstedt said the child may have injured herself by hitting her face on a desk or hitting her head in her crib.

Nordstedt was alone with the girl while her mother worked when he called for an ambulance and said the child was having trouble breathing because of a possible allergic reaction.
