Let's keep things in perspective. It is not like Parkin killed his mom. Afterall, Irene Prusik died in September 2003. Case report. But questionable conduct by Parkin may extends to the time his mom was still living. For example, in 1996, Prusik apparently gave the deed of a building his mom owned in the Park Slope section of Brooklyn to her son. By 2000, Parkin was apparently in debt over some bad reality investments. Perhaps by forging his mother's death certificate with a false Social Security number and birth date, he sought to keep his financial security blanket alive? Since she was already apparently "helping him" with his finances, how natural for him to continue to collect her Social Security. Similarly, why not sue in her name? Afterall, the defendant bought mom's building in a foreclosure action. Say what you must about our legal system; however, this litigation is apparently how authorities discovered Parkin's alleged wrong doing.
5-6-2013 Update: Thomas Parkin was convicted May 3 on charges including grand larceny and mortgage fraud. He was sentenced to 13 2/3 to 41 years in prison.
