During our periodic check of court files in cases we’re following, we just found out that a West Seattleite arrested and charged with murder in a shooting death near Sea-Tac has pleaded guilty to a reduced charge. We reported in December on the arrest of 39-year-old Aaron Parypa at his Junction-area home; he was subsequently charged with second-degree murder and first-degree assault for a deadly shooting in October that prosecutors said was preceded by an attempted marijuana sale. According to court documents, Parypa, who had no previous criminal history, pleaded guilty last Friday to the reduced charge of second-degree manslaughter. In a written statement accompanying his plea, he wrote, “Although I do not believe I am guilty of manslaughter because I acted in self-defense, I want to plead guilty to the charge to take advantage of the reduction of the charge and the prosecutor’s recommendation.” The same document lists the standard sentencing range as 21 to 27 months.
