(Oklahoma City-AP) -- A member of a prominent Oklahoma family has been ordered to spend 15-years in prison.
An Oklahoma County judge gave Joffa Kerr a 15-year prison sentence today.
Kerr is the granddaughter of the late Robert S- Kerr, a former U-S senator and co-founder of the Kerr-McGee oil empire.
She pleaded no contest to two counts of first-degree manslaughter stemming from a drunken driving case.
Prosecutors say her blood-alcohol level was more than twice the legal limit when her vehicle collided head-on with a van.
Sixty-five-year-old Phillip Lopez and his 12-year-old grandson Ryan J- Dawson were killed in the accident.
