MANDAN, N.D. (AP) — A combined memorial service will be held for a North Dakota business owner and three employees found slain earlier this week.

The service for Robert Fakler, William and Lois Cobb, and Adam Fuehrer will be held Tuesday morning at Bismarck Community Church.

Their bodies were discovered early Monday at RJR Maintenance and Management in Mandan, a city just across the Missouri River from Bismarck. Police have classified the case as a "multiple homicide," but investigators haven't said how the four died or identified the suspect.

Fakler co-owned the business, while the Cobbs and Fuehrer were employees.

Eastgate Funeral and Cremation Service director Bob Eastgate tells the Bismarck Tribune the families decided to have a combined service because the four were good friends.

The memorial service is open to the public.
