POPLAR BLUFF, Mo. -- Authorities are searching for two men they believe robbed Sonic Drive-In employees at gunpoint early Wednesday.

About 1:05 a.m., two female employees exited the South Westwood Boulevard restaurant after locking up for the night and were standing outside talking, Poplar Bluff Police officer Bryce Colvin said in his report.

One of the women, Colvin said, noticed her co-worker stop talking and saw two men, wearing black clothing and hoods, walk around the south end of the building.

"One of the suspects pointed a gun at her and she backed up and threw her keys and purse and bank deposit bag," Colvin said.

The suspect, according to Colvin, ran toward the woman, grabbing her purse and the deposit bag.

"She heard footsteps as both suspects fled back around the south end of the building," Colvin said. At that point, Colvin said, the woman reported grabbing the "business keys."

The women "ran back into the building," relocked the door and let the alarm sound, Colvin said. A call was made to 911.

Upon their arrival, Colvin said, officers conducted an area search, but the suspects were not found.
