(AP) — Former Nebraska state Sen. Bob Kremer has died at age 77.

Kremer, of Aurora, died on Tuesday of an apparent heart attack.

Kremer served in the Legislature from 1999 to 2007. He grew up on a family farm south of Aurora, and spent his life as a cattle feeder.

His son, Mark Kremer, says the former lawmaker enjoyed working with people and was involved with several agriculture groups, including the Corn Growers Association, Nebraska Farm Bureau and Nebraska Cattlemen. Kremer says his father was also deeply religious, and looked for ways to encourage others.

A visitation is scheduled Friday from 4 p.m. to 7 p.m. Friday at Pleasant View Bible Church in Aurora. A celebration of life will be held at the church at 11 a.m. on Saturday.
