East Lee was a 19-year-old member of the Cheyenne River Sioux Tribe whose body was found at Brueske Lake near Eagle Butte, South Dakota, on October 20, 2015. Investigators determined he died of a single gunshot wound to the head and believe the killing occurred on October 19 or October 20; he was reportedly last seen at a residence in Eagle Butte after midnight on October 20. The FBI led the homicide investigation and offered a $5,000 reward for information; the Cheyenne River Sioux Tribe later matched that amount, bringing the total to $10,000.

Months after the death, family and community members held a Justice for East Lee march in Eagle Butte. No arrests have been announced and no suspects have been publicly identified, and the investigation remains open.

Does anyone with knowledge of East Lee, his movements in October 2015, or the Eagle Butte area at that time have information to share?
