TYLER (AP) – A jury has returned a 20-year prison sentence for a retired Tyler dentist convicted of murder in his wife’s death. Prosecutors had been seeking a life sentence for 76-year-old Bobby Ray Nichols in the shooting death last summer of Rosalind Nichols, his wife of 26 years. However, the Smith County jury found Nichols acted out of “sudden passion” when he shot his 71-year-old wife at their home last June. Nichols will become eligible for parole after 10 years in prison. In his closing, defense attorney argued that Nichols was abused by his wife and that he killed her in a fit of passion. Prosecutor Richard Vance argued that any sentence less than life would suggest a tacit endorsement of Nichols’ actions.
