A Lincoln High School student was shot and killed in Sioux Falls on Saturday night, and police are still searching for a suspect.

An email to Lincoln High parents from principal Laura Raeder identified the victim as Venance Kitungano, 18.

Kitungano was shot and killed Saturday night in the area of Eighth Street and Indiana Avenue after attending a Halloween party at the Red Sea Pub, Lt. Terrance Matia said.

Kitungano stepped outside the building and was walking down the street when he was shot once in the face, Matia said.

Matia said Kitungano was not involved in any altercation and that he was an "innocent bystander" and an "unintended victim."

Police have not released any details about potential suspects and are urging witnesses to come forward. Matia said it's likely there are children who attended the party and know who the shooter was.

He said the shooter was likely using a Halloween costume as a disguise, but "it doesn't matter because we are going to find out who did this."
