York City man is being sought in connection with the death of his 11 month-old baby boy.

Investigators are searching for Yohan Alfredo Ramirez-Herrera, 26, of York City.

On Saturday, the baby was rushed to York Hospital and later transferred to the Penn State Hershey Medical Center.

The baby was taken off of life support on Tuesday morning.

An autopsy conducted on Wednesday showed that the infant died of multiple blunt force trauma.

Dauphin County Coroner Graham Hetrick says this was clearly a sign of abuse, and not an accident.

" Believe me. its not an easy thing to sit there and perform an autopsy on an 11 month old child and look at th innocence of that body and see what's done to it is a pretty horrifying thing," says Hetrick

Neighbors of Herrera say he and his wife were quiet people. One described him as "strange."

York City Police are asking anyone with information on Herrera's whereabouts to call them.
