According to the Dallas Police Department blog, the man –– a 60-year-old Corinth resident named Douglas Lee Leguin –– began taking shots at Dallas firefighters on Monday as they arrived near the scene of a reported Dumpster fire in the well-to-do neighborhood. The firefighters were not hit and put out a call for assistance.

In short order, the Dallas SWAT team and a host of police officers descended upon the scene, and the man continued to fire shots. However, no officers were injured in the incident. Eventually, negotiators persuaded the man to surrender.

Leguin was charged with seven counts of aggravated assault. According to the Denton Record-Chronicle, he had placed a number of explosive devices around the property where he engaged police in the standoff. Those devices were defused or detonated. Reportedly, the same man had encountered a babysitter in the neighborhood with an 8-year-old girl and had threatened both of them before starting his rampage.

According to the Dallas Morning News, Leguin had called police during the standoff to tell them that he belonged to the antigovernment “sovereign citizens” movement, which believes that most government institutions are illegitimate, as are the laws they enforce.
