A deckhand on the fishing vessel Alaska pleaded guilty Jan. 22 to stabbing another crew member in a 2007 incident and is facing a 13-year prison term. Robert David Legerrette, 69, accepted the stipulated sentence for the Aug. 11, 2007, stabbing of David Cunningham, 52, while the ship was moored at 750 North Harbor Drive around 5:50 a.m., according to court records. Cunningham was stabbed in the chest. San Diego Superior Court Judge David Danielsen set sentencing for March 19. Legerrette wrote in a court document that he “did unlawfully commit assault with a deadly weapon by means likely to cause great bodily injury.” The motive for the assault is unknown, according to a prosecutor. Legerrette was also accused of being under the influence of Vicodin, codeine and morphine at the time. Those charges and an attempted murder count were dropped in a plea agreement. Part of the reason Legerrette’s sentence is lengthy is because of his criminal record. He was convicted of robbery in 1971, as well as attempted theft in 1997 and burglary in 2000, according to records. Legerrette fled the ship after the assault, forcing San Diego Harbor Police to distribute fliers with his picture. Later that day, paramedics were trying to deal with an “unruly person” identified in the flier as Legerett. Harbor Police responded and arrested him. Legerrette remains in jail without bail.
