Authorities say they are continuing to search an area in southeastern South Dakota for a Florida prisoner who escaped from a transport van at an interstate fuel stop.
The Highway Patrol says 31-year-old Oscar Antonio Herrera-Menjivar was being taken to a Nebraska facility by a private prison transport company when he escaped about 2 a.m. Saturday. The van had stopped at a fuel station off Interstate 90's Exit 353, near Spencer.
Authorities said Sunday they were continuing to pursue leads in the case and warned the public that the prisoner should be considered dangerous. He's described as 5-foot-5, 140 pounds with black hair and brown eyes.
The patrol says Herrera-Menjivar was originally charged with sexual assault of a minor.
