Alexander Alex Umansky was 35 and lived in Sherman Oaks, Los Angeles when he was murdered on March 18, 2002. A proprietor of a car stereo and electronics store and known within the Russian community, Umansky was lured to a home under the pretense of installing audio equipment in multiple cars. There he was ambushed, killed, and later disposed of in New Melones Reservoir in Northern California.

His murder was one of several kidnappings-for-ransom carried out from late 2001 into early 2002 by a group of Russian immigrants led by Jurijus Kadamovas and Iouri Mikhel. Prosecutors described a scheme in which wealthy community members were abducted, ransoms demanded and paid in some cases, yet victims were killed and their bodies weighted and dumped in the reservoir.

If anyone knew Alex, saw him on or just before March 18, 2002, or has information about his abduction, please come forward.
