PHOENIX -- A man accused of carjacking several vehicles while naked and causing crashes that injured seven people in Scottsdale has been sentenced to 8 1/2 years in prison.
Maricopa County prosecutors say 46-year-old John Hugh Brigham of Gilbert also was sentenced Friday to five years' probation.
They say the ex-real estate agent and high school teacher entered into a plea agreement and pleaded guilty to theft of means of transportation, aggravated assault and three counts of endangerment.
Police took Brigham to a hospital for an evaluation after the June 2012 incident and a toxicology test showed he had the drug PCP in his system.
Witnesses say the carjacker exited a vehicle after the first crash, took off his clothes and stole another vehicle. A pregnant woman was among those injured.
