Washoe County District Attorney Chris Hicks has thrown the book at a man convicted of his 7th DUI. 37 year old Joseph Estrella of Incline Village has received the maximum sentence of 15 years in prison after being convicted again of driving under the influence offense. The prior convictions spanned 19 years and involved misdemeanor and felony convictions in multiple California and Nevada jurisdictions. The sentence ensures that a minimum of 6 years must be served before parole eligibility begins. Testing of Estrella’s blood after his arrest detected both marijuana and methamphetamine.
