Several people found dead of unknown circumstances inside North Dakota company

On Monday, several people were found dead at RJR Maintenance and Management, a property management company, according to Fox News.

The company is located in North Dakota. Police say that it is unclear how many people died, and the cause of death is not known at the moment.

Several people have commented on their Facebook page which noted that they would be closed for the day.

"The Facebook post has generated dozens of comments, including one from someone who says both their parents work at the company, and that neither have been reachable," a report from Crime Online said.

The police asked to look at surveillance video from another company in the area.

"Darin Helbling, a manager at a nearby bowling alley, said police asked to see his business' surveillance video. He said the video showed only a couple of vehicles on the road that separates the businesses since 10 p.m. Sunday," Fox News reported.

After a press conference, police said that the bodies of three males and one female were found. However, the bodies have not been identified and families have not been notified.

"No one is in custody at this time and law enforcement is still investigating," reported KFYRTV.
