A suspect has been arrested and faces multiple charges in relation to a homicide that occurred in Charles Mix County last week. The South Dakota Division of Criminal Investigation, Yankton Sioux Tribal Law Enforcement, and the Charles Mix County Sheriff’s Office all worked together to coordinate the apprehension of Mackenzie Antelope, 18 of Lake Andes, SD. Antelope has been charged with murder and manslaughter in the death of Quinlan Ream, 22 of Lake Andes, SD. Antelope has also been charged with aggravated assault against Dylan Oullette, 33 of Lake Andes, SD. This case is a prime example of Tribal, State, and County governments working together. Due to this collaborative effort law enforcement officers from multiple agencies were able to act swiftly in order to protect the public. Antelope is currently being held at the Charles Mix County jail on a $500,000.00 bond. He is scheduled for an initial appearance in court next week. Defendants are presumed innocent under the U.S. Constitution until proven guilty.
