MINNEAPOLIS (AP) -- A minister has been sentenced to prison for driving drunk and killing a woman who was on her way to work as a Minneapolis 911 dispatcher.

Seventy-three-year-old Richard Shaka, a former college professor, was sentenced to a four-year term Tuesday in Hennepin County District Court for a February 2018 crash that killed 30-year-old Jenna Bixby on a Brooklyn Park highway.

With time spent in jail, Shaka will serve the first 2? years in prison and the balance on supervised release.

Prosecutors say Shaka had a blood alcohol content of 0.16 percent _ twice the legal limit for driving in Minnesota _ when he crossed into Bixby's lane and struck her vehicle.

Shaka taught theology at North Central University in Minneapolis from 1996 until 2011.
