SIOUX FALLS, S.D. (KELO.com) — Sioux Falls Police have released a portion of the security footage of a Halloween-masked armed robber at the Casey’s at East Rice Street and North Jessica Avenue early Sunday morning.
The clerk who was robbed said robber’s skin was covered so authorities do not have information about his ethnicity that could assist in an identification.
The robber had a knife, got an undisclosed amount of cash, then left the store.
The robber remains at large.
