A Parkdale man was arraigned Monday on attempted murder and assault charges for the shooting of a man at the Hood River Marina early Saturday evening.  Hood River Circuit Court Judge John Olson set bail at $50,000 for 28-year-old Tyson Sackett, accused of shooting 60-year-old Mark Wright of Eugene.  Hood River Police say officers responded to a report of shots fired at the Hood River Marina around 6:45 p.m. Saturday.   According to witnesses a man fired several shots at another man in a vehicle at the north end of the marina.  The gunman fled eastbound across the marina, stripped off his clothing and jumped into the Columbia River and swam to the adjacent riverbank.  Hood River Police located Sackett and took him into custody a short time later at a nearby gas station.  A Skamania County dive team on Sunday morning retrieved a handgun believed to have been used in the shooting from the Columbia River near the north end of the Hood River marina.  Wright was able to drive himself into the downtown Hood River area before getting help, and was transported by Life Flight to a Portland area hospital.  Sackett will make his next court appearance on May 12.
