Eight years ago while investigating the death of a 2 1/2-year-old girl investigators knew the toddler had been murdered but didn't have enough evidence to file charges in the abuse case a judge later called ''unfathomable.''
That began to change last year when police were called to the same house to investigate reports a 3-year-old boy had been beaten and abused by his father, McKinley Warren Jr.
The injuries to both children were strikingly similar and they laid the groundwork for deeper questioning of Warren and his wife that provided insights into how the family functioned and the father's penchant for harsh discipline.
Following a grand jury investigation, the parents were each arrested and his wife later agreed to agreed to testify against her husband.
Warren struck a deal with prosecutors, pleading guilty to third-degree homicide in the death of Jessica and aggravated assault in the beating of his son, Isaiah Warren. Under the deal, he dropped his right to appeal and was immediately sentenced to 25 to 50 years in state prison.
''What you did to this child are the actions of an animal,'' the judge said.
The doctor who examined the toddler determined the brain injuries she suffered looked like she had been in a 20-30 mph car accident.
Assistant District Attorney Michael Mancuso said Warren's case was the worst child abuse case he had ever prosecuted.
Jessica had been losing weight and her flesh appeared to be wasting away in a household where McKinley Warren took potty training problems as a sign of deliberate defiance from his children and beat them, Assistant District Attorney Michael Mancuso said. The father also taunted his son for acting ''like a woman.''
After Jessica's death McKinley Warren told police his daughter injured her head in a fall out of a parked vehicle.
After police began investigating injuries to Isaiah Warren, Cindy Warren, 30, told investigators that her husband made up that story on the way to Pocono Medical Center and told her to stick to it or she ''will go down with him,'' police said.
She later told police on the day Jessica died, Warren had been drinking at a nearby bar and she called him to come home to change her diaper. WTF??
His wife said she heard him upstairs yelling, then heard the sound of a smack and later saw Jessica had been ''knocked out.''
She pleaded guilty to endangering the welfare of children and is awaiting sentencing.
Warren apologized to his wife and family before leaving the courtroom.
