On January 30, 2013, a free-ranging 11-year-old female moose (Alces alces) was captured, equipped with a satellite-linked global positioning system collar by the Minnesota Department of Natural Resources, and released. The moose was part of a study to examine the causes of death in Minnesota's declining moose population. A mortality signal was emitted from the collar on December 7, 2013. The carcass was found intact without signs of predation or scavenging, was extracted from the field, and underwent necropsy at the Minnesota Veterinary Diagnostic Laboratory 2 days after the mortality signal was first received.
