On September 29, 1879, Ute warriors killed Indian agent Nathan Meeker and ten male employees at the White River Agency in Colorado while simultaneously ambushing U.S. Army troops under Major Thomas T. Thornburgh at Milk Creek, killing him and 13 soldiers. The conflict led to the forced removal of the White River and Uncompahgre Utes from Colorado.
The files run from 1864 to 2023. The 2010s hold the most, with 10 files. The oldest is White River War, from 1879.
They are spread across 20 cities and towns; the most are in Colorado Springs (3), Denver (3) and Boulder (2). By type, the largest groups are murder and homicide cases (23), mass shooting cases (6) and kidnapping and abduction cases (3).
16 files of the 26 have coverage attached: 59 videos, podcasts and documentaries from 18 creators. Kendall Rae, Dr. Todd Grande and Stephanie Harlowe have covered the most of them.
Every file is written from cited sources and pinned where it happened, and every person named carries the legal status the record gives them. If you hold information about an unsolved case, contact the investigating agency named in its file rather than posting it publicly. Families and anyone involved can request a correction from any file.
