GRAND RAPIDS, Mich. (AP) — A 59-year-old former Michigan teacher who authorities say had a sexual relationship with a then-16-year-old student in 2010 is expected to keep getting his pension from the state.

WOOD-TV reports that the state Department of Education says Krag Sanford's annual pension payment is about $21,000.

The ex-Saranac High School teacher was sentenced Tuesday to six months behind bars in Kent County. The jail time will run at the same time as a nine month sentence in Ionia County.

Plea agreements resolved the cases.

The man from Kent County's Byron Township was arrested after authorities said he had a sexual relationship with the teen. A letter presented earlier in court says he impregnated her this year.

The Grand Rapids Press reports she's now 18 and the pair plan to get married.
