A Douglas County judge Tuesday morning sentenced a 22-year-old Bonner Springs man to serve two years probation for his role as the driver in a January robbery of four Kansas University students outside a Lawrence Burger King.

If he violates his probation, Antoine Barber will have to serve a two-year prison term, Chief District Judge Robert Fairchild said. Barber pleaded guilty earlier this month to two counts of attempted robbery after prosecutors originally charged him with four counts of aggravated robbery.

A co-defendant, Nicholas G. White, 20, of Kansas City, Kan., who faces four aggravated robbery charges, will appear in court in June. Prosecutors accuse White of demanding cash at gunpoint from the four students in the early morning hours of Jan. 25 as the students were waiting for food in the drive-through lane at the restaurant near Sixth and Missouri streets.

Defense attorney Tim Riling said Barber was the designated driver that night, and he was unaware anyone would try to commit a robbery. But after the incident occurred, the victims said the robbery suspect then got into a car that left the scene, and police arrested Barber days later and identified him as the driver.

“If he had to do it over again, he would probably choose to take a different course of action,” Riling said.
