Man charged in son's death 23 years after shaking him

Christopher Barber served nearly five years in a Pennsylvania prison in the 1990s for shaking his fussy baby boy and flinging him onto a couch so hard that he suffered catastrophic brain damage.

[...] Barber is behind bars again, charged with homicide, following his son's death at age 23 after he lingered in a vegetative state the rest of his life, hooked to a breathing machine and fed through a tube.

Prosecutors had him arrested after a pathologist ruled Christopher Kostenbader's death last May a homicide, saying he succumbed to "complications due to the severe head injury that occurred in 1991 at the hands of the defendant."

The infant was taken to the hospital, where doctors found "tons of damage" to the brain, bleeding behind the eyes and rib fractures that led them to diagnose shaken baby syndrome, court documents said.
