A man who may be paralyzed from the waist down because his grandfather fired a shotgun at his back earlier this month has had his condition upgraded from serious to satisfactory.

Joshua Stone, a 27-year-old from Champagne, Ill., arrived in Tahoe on Aug. 15. He and his grandfather, David Lee Bayless, 70, began drinking the next day until the shooting occurred at 1:20 a.m.

Bayless told police he shot his relative because he believed Stone was going to harm a woman visiting his Tahoe Nugget apartment. The woman, who lived in the same apartment complex as Bayless, was not injured during the incident.

Stone called 911 as he lay injured. He was transported by helicopter from Barton Memorial Hospital to Washoe Medical Center. Officers questioned Bayless after the shooting but did not arrest him.

Police delivered their investigative reports to the El Dorado County District Attorney’s Office on Wednesday. Deputy District Attorney Anthony Sears said his office will be reviewing the report and probably by next week will decide if anyone involved in the shooting will be charged with a crime.
