A north Minneapolis husband and wife who died in a traffic collision in Wisconsin are being remembered in a memorial service Wednesday before burial at a military cemetery.

Dennis Holman, 68, and Jeanne Holman, 65, of north Minneapolis, were traveling in rural east-central Wisconsin over Labor Day weekend, when their car struck a pickup truck, according to the Sheboygan County Sheriff’s Office. The Holmans were both dead at the scene, the Sheriff’s Office said.

The pickup’s driver, Kenneth Knepfel, 55, of Plymouth, Wis., was airlifted to a hospital with serious injuries, authorities said.

Dennis Holman was driving his car west on County Road C late in the morning on Sept. 5, failed to observe a stop sign and hit the pickup in the intersection with County Road AP, according to the Sheriff’s Office. The Holmans’ vehicle ended up on its roof, and the pickup slid into a ditch.

Dennis Holman served with the Minneapolis Fire Department for 30 years until 2009, retiring as a department vehicle operator.

Following the service for the Holmans at Hope Lutheran Church, 5200 Emerson Av. N., Minneapolis, the husband and wife of 39 years will be buried at Fort Snelling National Cemetery.
