Camp Liberty shooting
American mass murder
On May 11, 2009, five United States military personnel were fatally shot at a military counseling clinic at Camp Liberty, Iraq by Army Sergeant John M. Russell. In the days before the killings, witnesses stated Russell had become distant and was having suicidal thoughts.
Russell was charged with five counts of murder and one count of aggravated assault. Officials stated there was an argument at the Camp Liberty Combat Stress Center and Russell was being escorted back to his unit at Camp Stryker when he took an unsecured M16 rifle from his escort, drove back to the clinic, and opened fire on unarmed personnel.
Background
Sergeant John M. Russell (born 1965) was serving his third tour of duty in Iraq as a communications NCO with the 54th Engineer Battalion. According to a fellow NCO, Russell was a quiet soldier who seemed to have trouble with new computer systems and learning how to make repairs. Russell was "very good" with traditional radio devices, but a lack of new skills degraded his performance and relationship with peers. Over time, the NCO said Russell became increasingly distant and visibly disturbed. He had been previously diagnosed with depression and dyslexia. In the days before the killings, witnesses said Russell became distant and started having suicidal thoughts.

Why this record matters
“Camp Liberty shooting” is worth following because a concise public description often conceals a longer documentary argument. Here, Camp, Liberty and shooting provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 10, 2026. The linked authority identifier is Q5027352. The first chronological checks are 2009 and 1965.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
