Charles Tyberg, whose conviction in the February, 1983, slaying of a San Diego police officer was overturned, pleaded guilty Wednesday to second-degree murder under terms of a plea bargain.
Tyberg, 20, adopted son of a deputy sheriff, was immediately sentenced by Orange County Superior Court Judge Myron Brown to a term of 17 years to life in state prison. Deputy Dist. Atty. Gary Rempel, the prosecutor in the case, said Tyberg must serve a minimum of 8 1/2 years, minus the four years he has spent in custody, before he is eligible for parole.
Tyberg was convicted of first-degree murder three years ago in the shooting death of Officer Kirk Johnson. Tyberg shot Johnson while on a joy ride in his father's patrol car. After the trial--held in Orange County on a change of venue because of extensive publicity about the case in San Diego--Tyberg was sentenced to 27 years to life in prison.
But last June the conviction was thrown out by the 4th District Court of Appeal, which found that homicide detectives feigned friendship to trick the youth into confessing. The court ruled the confession inadmissible in Tyberg's second murder trial, which was scheduled to begin April 20.
