Judy Praus, 70, said she was a longtime friend of the owner’s family and had just seen them at a restaurant Saturday. She said she also knew a lot of employees, and had no details on any of them. “When I was notified, I shattered. Unbelievable,” she said. Gina Kessel, 52, of Mandan, showed up at the business to pick up her son, Mitchell Kessel, an employee there. She said Mitchell “called me, said something is going on.” She said he didn’t tell her what. The pair hugged, with both of them crying. Her son declined comment before going back behind a police line. A statement posted on the company’s website said the business was closed Monday. No one answered the phone at the business, which is somewhat isolated despite its location in a business district near a busy main road known as The Strip. A large empty lot sits in the front, a golf course in back and a soccer complex to one side. Darin Helbling, a manager at a nearby bowling alley, said police asked to see his business’ surveillance video. Helbling said the video showed only a couple of vehicles on the road that separates the businesses since 10 p.m. Sunday. RJR’s website identified it as a family-owned company that has been handling commercial and residential properties in Bismarck and Mandan for more than 20 years. Its services include collecting rent for landlords, paying mortgages, re-renting apartments, building and grounds maintenance, lawn care, and snow removal. It also rents out storage units.

The bodies of three men and one woman were found Monday morning. A North Dakota town was devastated after four people were found mysteriously dead at a local business and police said they were searching for the suspect. A homicide investigation is underway after the bodies were found Monday morning inside RJR Maintenance & Management, a property management company in Mandan, said the Mandan Police Department. Two of the victims, employees Lois Cobb, 45, and William Cobb, 50, were married, Mandan Chief of Police Jason Ziegler said at a news conference on Tuesday. Robert Fakler, 52, the owner, and Adam Fuehrer, 42, another worker, were also among the dead. "We just don't have answers," Ziegler told ABC News, adding that no suspects have been identified and no one is in custody. "It's very unusual for the state of North Dakota. I don't think any community across this great country could ever imagine something like this happen in their backyard," he added, calling the crime "devastating" for the community. Ziegler said police do not believe the public is in danger, but he urged the community to remain vigilant. "This was very specific to the victims that were involved," the chief said. "There was nothing at the crime scene that would lead us it believe that anyone outside the victims involved are in any danger." The chief called RJR Maintenance & Management a "reputable company in our area." There were security cameras inside the building but the chief did not say if the crime was on video. No weapons were recovered, he said. Autopsies are being conducted and cause of death will be released by the medical examiner, Ziegler said. As police investigate, Ziegler said, "We're asking for public assistance. If anyone has any information regarding this crime, please contact the Mandan police."
