A single-punch assault in Waikiki last year that left a victim permanently disabled resulted this morning in a one-year prison sentence and five years probation for the attacker.

Defendant Ryan Carrillo received the sentence from Circuit Judge Richard Pollack today after being convicted earlier in the nonjury trial.

Deputy Prosecuting Attorney Chris Van Marter said the sentence "grossly minimized the crime the defendant committed."

Carrillo had been accused of throwing a "superman punch" to Jesse Greenwood's head last February on the sidewalk outside Moose McGillycuddy's Pub & Cafe.

Carrillo had originally been charged with second-degree attempted murder. Both men were visiting from California when they became involved in an altercation inside the nightspot that later spilled to the street outside.

During the trial, Van Marter said Carrillo launched "a very violent and cowardly attack" on Greenwood by running at him from behind, jumping in the air and punching him on the left temple.

Greenwood, 29, was knocked unconscious by the blow and fell to the pavement, striking his head on the curb, said Van Marter.

He suffered multiple skull fractures and "catastrophic brain injury" that led to numerous surgeries including a partial lobotomy, Van Marter said during the trial.

Defense attorney Michael Green said during the trial that Greenwood was extremely drunk and had caused problems in Moose McGillycuddy's, bothering Carrillo and his friends, including at least one woman.

"This guy was a mean drunk," Green said of Greenwood.

Greenwood was escorted from the premises by security personnel, then allowed back in to pay his bar tab, then once again escorted outside, Green said.

When Carrillo and his friends emerged from the nightclub, Greenwood approached them on the street and another scuffle ensued, with one of Carrillo's friends grabbing Greenwood and pulling him to the ground.

Carrillo "had had enough and decided to punch or tackle this guy once," said Green. "There was never any intent to kill anyone."

Greenwood and his family have filed a civil suit against Carrillo and others, including the owners of the nightclub.
