A person has been arrested in connection with the fatal shooting of an Oglala Sioux Tribe police officer over the weekend, according to tribal authorities.
Officer Brian Garrett, 52, of Kyle, was shot around 4 a.m. Saturday in what investigators believe to be a domestic dispute while he was off duty.
Emergency personnel administered CPR on Garrett, but he was declared dead after being transported on a medical helicopter, according to a release from the Oglala Sioux Tribe Department of Public Safety.
It says the suspect's name is being withheld while an investigation is conducted by tribal police, the federal Bureau of Indian Affairs and the FBI.
The FBI, in a tweet Saturday afternoon, said the officer "was shot and killed during an apparent domestic dispute."
Tribal police said they responded to the incident after receiving a call about a "domestic situation and a person being shot" at a residence east of Kyle. The suspect was arrested at the scene and is in custody, they said.
The FBI declined to provide additional information about the case, and acting tribal police chief Mark Mesteth couldn't immediately be reached for comment.
