A jury found William Wright III not guilty of second-degree murder and voluntary murder.
The jury was hung on a third charge of involuntary manslaughter.
Officials say Wright shot and killed his son, 31-year-old William 'Billy' Wright IIII, at a home in Fresno in 2022.
After Friday's verdict, Wright III's bail was reduced to $10,000.
He is expected to be back in court for a hearing on the third charge on Monday.
