Chad Hutson Littlefield, 35, was killed on February 2, 2013, at the Rough Creek Ranch–Lodge–Resort shooting range near Glen Rose, Texas. He had been at the range with friend Chris Kyle to help Eddie Ray Routh, a 25-year-old Marine veteran who had been diagnosed with schizophrenia and had been in and out of mental hospitals.

Littlefield lived in Midlothian, Texas, and worked as a facilities and logistics manager at Eagle Labs, Inc. He is survived by his wife, Leanne, and their daughter, Morgan. Routh was arrested and charged with capital murder; at trial he said he shot them because he felt they were a threat.
