South Dakota law enforcement alarmed the state into a manhunt yesterday morning following a multiple shooting in Sisseton:

State and local Law Enforcement are searching for Colter Richard Arbach, 22, Sissteton, the subject in a quadruple homicide. The shooting incident occurred in a Sisseton residence early this morning. Four individuals are dead and one is critically injured. The names of the victims are not being released at this time.

Arbach is armed and dangerous and should not be approached. Anyone who has seen Arbach or knows of his whereabouts is asked to contact the Sisseton Police Department at 605-698-7667 [South Dakota Attorney General's office, press release #1, 2014.11.22, approx. 6 a.m.].

About three and a half hours later, law enforcement found their suspect... dead at the scene of the crime:

The Division of Criminal Investigation has located and identified Colter Richard Arbach, 22, Sisseton, as one of the deceased individuals at the scene of the shooting incident that occurred at a Sisseton residence early this morning. Preliminary investigation results identify Arbach as the shooter, before taking his own life. Investigators are continuing to locate other individuals who may have been at the scene at the time of the shooting for their involvement or their eyewitness account. Law Enforcement does not feel that the public is in danger at this time.

The investigation is still ongoing. Agencies assisting in this investigation are the Sisseton Police Department, Sisseton-Wahpeton Sioux Tribal Police, Roberts County Sheriff’s Office, South Dakota Highway Patrol, South Dakota Game, Fish and Parks and the Division of Criminal Investigation [South Dakota Attorney General's office, press release #2, 2014.11.22, tweeted 9:32 a.m.].

Before whipping the public into a panic, maybe law enforcement should check IDs on the bodies one more time. If investigators knew enough to peg Arbach as the shooter, if they had a description and a photo, then whoever they were talking to at the scene probably would have known enough to ID the perp at the scene.

Keep calm, and carry on.
