Robert Raubenolt-Crumm, 34, was found dead at the Mocks Arch Apartments in Summerville, South Carolina, on March 10, 2015. A veteran of the U.S. Army and the Ohio National Guard, his death prompted a Dorchester County Sheriff’s Office investigation that quickly identified a person of interest.

Authorities arrested David M. Ravenel after reports say he resisted officers during the apprehension. Ravenel was charged with murder in the shooting death of Raubenolt-Crumm. Prosecutors presented their case at trial, a jury returned a guilty verdict, and Ravenel received a lengthy prison sentence.
