The 2007 disappearance of Irina Malezhik led to the arrest of Dmitriy Yakovlev, who was suspected of the 2005 murder of Viktor Alekseyev and the 2003 disappearance of Michael Klein. 

Fresh eyes would help the N.Y.P.D. and state police investigators find a man suspected of the 2000 and 2005 murders of Dora Almontaser and Angel Serbay, respectively. 

Investigators wondered if the motive behind Jonathan Levin's homicide was connected to the victim's incredibly wealthy father, until a message left on an answering machine led them closer to the truth.

N.Y.P.D. detectives investigated whether the death of Borys Kiejliches could be related to a murdered Russian man found along the Staten Island shoreline, both of whom were found on the same day.
