OTTAWA – The Canadian Forces National Investigation Service (CFNIS) has charged one military officer late yesterday with an offence relating to the death of a presumed insurgent in Helmand Province on or about October 19, 2008.

Captain Robert Semrau was charged with one count of second-degree murder, contrary to Section 130 of the National Defence Act, pursuant to Section 235(1) of the Criminal Code. Captain Semrau was a member of the Operational Mentor and Liaison Team at the time of the incident. He is accused of shooting, with intent to kill, an unarmed male person. Captain Semrau is currently in Military Police custody and will be transported back to Canada shortly for a hearing before a military judge to determine whether he is to be retained in custody.

The Commander Task Force Kandahar was made aware of the allegations on December 27, 2008 and notified the CFNIS who immediately initiated an investigation. The CFNIS laid the charge after analyzing the evidence and interviewing witnesses. As the matter is now proceeding in accordance with the Code of Service Discipline, and another part of the investigation is still ongoing, it would be inappropriate to comment further at this time.

The CFNIS is an independent Military Police unit with a mandate to investigate serious and sensitive matters in relation to National Defence property, Departmental employees and Canadian Forces personnel serving in Canada and abroad....
