Father accused of hitting, killing his 2-year-old son on Christmas Eve in Yonkers

YONKERS, New York (WABC) -- A father from Westchester County is under arrest, accused of hitting and killing his toddler son.

Police said Blair Robinson of Yonkers brought his unresponsive 2-year-old son Alex to the emergency room at St. John's Hospital on Christmas Eve. He told the staff he didn't know what was wrong with him.

But doctors noticed bruising and alerted police. The child was pronounced dead a short time later.

Through their investigation, Yonkers police said they determined that the toddler suffered blunt force trauma caused by Robin striking him, and that's what resulted in the child's death.

Robinson was arrested Wednesday and charged with first-degree manslaughter. He's expected to be arraigned on the charges later in the day.

"This was a particularly disturbing investigation for our personnel and I credit our patrol officers and detectives for their efforts and professionalism resulting in this arrest," Police Commissioner Gardner said in a news release.

Police also said that when they went to Robinson's house Maple Street, they found the boy's mother and a 10-month-old girl - and they were in unsanitary conditions. Their 21-year-old mother was not charged with a crime.

"The apartment was unsanitary, deplorable conditions -- filthy, no heat, no food," Gardner said.

The infant was removed from the home and turned over to Child Protective Service.

Neighbors say the boy's mother is eight months pregnant. They do not know where she is tonight.
