Authorities say a Minnesota man threw his newborn daughter four metres across his home's living room and into the kitchen, fatally injuring her.
The reason? She was being fussy, he told investigators.
John Peterson was arrested Tuesday, about three weeks after the death of his 5-week-old, who suffered head injuries that included a skull fracture, NBC affiliate KARE 11 reported.
Officials say Peterson, who has been charged with second-degree murder, lied to officers about how his daughter died. He initially told officers that the infant stopped breathing completely after being "fussy," KARE reported. He later said his daughter hit her forehead after he accidentally dropped her in the sink.
On Monday, after doctors concluded that Peterson's account didn't square with the severity of the infant's injuries, investigators questioned him about his story.
