Neighbors and officials had described Dykes as a survivalist with "anti-government" views.
Even as the hostage situation continued Monday morning, plenty of police were on hand as schools in neighboring Ozark, Alabama, reopened for the first time since the incident began.
Dale County schools remained closed but were to reopen on Tuesday, the district said.
In Ozark, school officials decided to begin strictly enforcing a 15-foot safety zone around school buses required by state law. The law prohibits any unauthorized adults, including parents, from approaching within 15 feet of a school bus stop. If an unauthorized adult gets too close, bus drivers are supposed to close bus doors or drive away, if necessary, school officials said
