A 34-year-old man from Indiana filmed 100 videos of himself suffocating and beating a toddler who almost died from the abuse. Christopher Keller, the toddler's stepfather has been jailed for 64 years after proof of him abusing his ex-wife's 18-month-old son.

After being notified by the 18-month-old toddler's mother, cops obtained a search warrant for Keller's home. Upon conducting the search, the police found over 100 hours of recorded abuse. The child's mother first realized that her son was being abused when she returned home from work to find her son with bite marks, severe bruises all over his body and a chunk of hair missing from his scalp. 

When the mother took the toddler to the hospital, she was told that the child had six fractures in her spine and that led her to contact the police. One of the videos shows the man dragging the little boy across the floor by his hair, pushing his head into a coach and also suffocating him for 40 seconds. 

David Sutter, the prosecutor was quoted by The Sun as saying the video was "extremely difficult to watch." It showed how the toddler was abused for an 11 hour period. Jefferson County Prosecutor's Office in a statement on Wednesday said that this was, "one of the worst documented cases of child abuse."

Speaking of Keller's punishment, Chief Deputy Prosecuting Attorney Blaine Goode said, "Maximum sentences are to be reserved for the worst of the worst offenders, and the torturous acts that the Court witnessed on the video today are the worst of the worst."

Keller had pleaded guilty to four counts of aggravated battery and as a result, was sentenced to 64 years in prison. He will be held prisoner at the Indiana Department of Correction with no eligibility to appeal convictions.
