Robert James Ingram was a 24-year-old Cobb County police officer killed just after midnight on July 13, 1993, in Marietta, Georgia, while investigating a suspicious person near railroad tracks in the Elizabeth area. The man approached wore dark clothing and carried a bag; when questions threatened discovery of a hidden .380-caliber handgun and ammunition, the encounter turned deadly. Ingram was shot twice in the head and became the first Cobb County officer killed by gunfire in the line of duty.

Authorities identified the shooter as George Russell Henry, a convicted felon recently released from prison and on probation for earlier burglary and forgery offenses. After the killing Henry stole Ingram’s patrol car, abandoned it near the Marietta City Club, and was captured later that morning on Atlanta Road south of Marietta. Henry confessed and pleaded guilty to the murder on the first day of trial; a jury recommended death, finding the killing was of a peace officer and done to avoid lawful arrest. Appellate records show the sentence was upheld and Henry remained on Georgia’s death row as of 2014.
