(AP) — A 26-year-old Lincoln man accused of slamming his 13-week-old baby son’s head into the bottom of a medicine cabinet has been given four to six years in prison.

Online court records say Victor Patterson was sentenced Wednesday by Judge Jodi Nelson in Lancaster County District Court. Patterson had pleaded no contest to attempted child abuse after prosecutors lowered the felony charge.

Patterson was arrested after the boy’s mother took her son to a Lincoln emergency room in March 2012 because the baby kept vomiting. Doctors say the boy had a skull fracture, five broken ribs, a lacerated liver and a broken collarbone.

Police say Patterson threw the baby into a coffee table, accidentally slammed the boy’s head into the medicine cabinet and squeezed him so hard the boy suffered internal injuries.
