The standoff is now over. The third person has come out of the trailer and has been arrested. Police confirm there was a meth lab inside the residence.
The Columbia police SWAT team has a trailer in north Columbia surrounded and neighbors have been evacuated over concerns of a meth lab.
The incident started when Blue Ridge Elementary was notified by a family member that there was a meth lab at the home of one of their students. The school then called police.
Police arrested an older juvenile and an adult when they got to the trailer, but they believe a suspect with felony warrants is still inside.
The SWAT team and negotiators are working to determine if anyone is actually still in the trailer.
