Waukegan, Illinois: Prosecutors will seek a life sentence for a suburban Chicago man accused of beating a 4-year-old girl to death after she spilled juice on an Xbox video console.

Prosecutors said "heinous" circumstances justify the sentence for 19-year-old Johnathan Fair, of Waukegan, if he is eventually convicted of first-degree murder in the death of his girlfriend's daughter, Skylar Mendez, the Chicago Tribune reported.

Fair was babysitting Skylar on December 13 at a Waukegan apartment when she was fatally injured.

He brought her to a hospital after she lost consciousness and initially claimed she'd fallen. She died a few days later at a Chicago hospital following surgery doctors had hoped would relieve swelling of her brain, the Lake County State's Attorney's Office said.
