Boy, 5, in coma following disturbing abuse

We have disturbing new details about a child abuse case involving a five-year old boy who police say is brain-dead after his mother's boyfriend admitted to throwing him across a room and into a dresser.
Albuquerque police tell us they arrested Richard Gutierrez, 31, on Tuesday after he called 911 to say the boy had "fallen off of his bed and was barely breathing.”
When police arrived at the home in The Villa Esperanza Apartment Complex, 3901 Lafayette NE, officers found the boy lifeless.
When asked what happened, Gutierrez told police that he had been watching his infant son and Desiree Gutierrez's son, his girlfriend and the mother of both children, while she was at school.
Gutierrez told police that he had asked the the five-year-old to get his brother a diaper in order to change him.
He said the boy got a diaper, gave it to Gutierrez and went back to his room to play. Gutierrez said that, a few minutes later, he heard a crash from the room and went in to investigate.He told police he saw the boy lying face up on the floor staring at the ceiling, apparently unconscious.
Gutierrez told police he tried several times to awaken the boy but didn't get a response.
He then said he took the boy into the shower and attempted to revive him with cold water.
Gutierrez said that’s when he called 911.
Later, however, in a recorded interview with police, Gutierrez said he “snapped” when the boy urinated on himself. He admitted that he threw the boy off a bed with great force. They boy’s head hit a dresser and a part of the bed. Gutierrez then said he picked the boy up from his underarms and put him in a bathtub with cold water to revive him.

The case of abuse is very sad in my opinion. There was much physical abuse towards the 5 year old. I believe there has to be another way to actually, "snap", he shouldn't have done those actions.
