[Mitochondrial DNA typing--a new level for solving identification problems in forensic medical expert identification of unidentified remains of victims of terrorist acts in Moscow and the armed conflict in the Chechen Republic].

Two large-scale episodes described in this paper reflect the first in Russia use of molecular genetic matrilinear markers (analysis of polymorphism of sequences of amplified fragments of mitochondrial DNA hypervariable locuses) in solution of a complex identification problem: forensic medical identification of unidentified fragments of victims of explosions of houses in Moscow in September, 1999, and of soldiers dead in the war conflict in the Chechen Republic in 1994-1996. The results of this work and methodological experience gained in it essentially extend the potentialities of expert studies as regards forensic medical identification of victims of large scale disasters, terroristic acts, and war conflicts.
