Jefferson Parish deputies say 23-year-old Cyril Jones bit a two-year-old girl, shook her, and threw her onto the ground.
According to deputies, it happened at a house in the 1500 block of Wakefield Drive in Marrero.
They say Jones told them that he lost his temper because the little girl was misbehaving.
After five days in the hospital, the little girl died Thursday night. According to deputies, she was the daughter of Jones’ girlfriend.
Jones now faces a murder charge.
