NAPA COUNTY, CA — A 21-year-old San Francisco woman allegedly driving under the influence crashed a borrowed Porsche in rural Napa County, killing her 18-year-old sister from North Carolina late Sunday night, according to the California Highway Patrol. Finnuala Hanifan was speeding south in the 1600 block of Atlas Peak Road south of Hardman Road east of Napa when she lost control and struck an irrigation culvert on the west side of the road around 10:45 p.m., CHP officials said.

The Porsche continued south and struck two wooden poles and a traffic signal, overturned and stopped on the west shoulder of Atlas Peak Road, according to the CHP.
