Anna Nicole Smith in alleged murder plot

In surprising news from the ongoing investigation into the untimely death of Anna Nicole Smith, the Huff Post is reporting that the FBI had suspicions the former  model and actress was plotting to kill her own son-in-law.

Smith, then 26, married Texan oil millionaire, J. Howard Marshall in 1994, but the 89-year old groom died a year later. Newly-released FBI files uncover an investigation conducted in 2001 into an alleged murder-for-hire plot which they believed Smith had created to kill Marshall’s son, and thus gain control of her late husband’s wealth.

From the day his father passed until his own death [from natural causes] in 2006, the son, Everett Pierce Marshall, waged a harsh legal war that blocked Anna from gaining her husband’s estate, judged at the time to be over $550-million.

As part of their plans, the FBI searched Anna’s home in July of 2000 and recovered a .357-caliber Smith and Wesson revolver and a stainless-steel knife. Agents then interviewed the model and the new records prove she broke down in tears at their allegations. She then made it clear that a murder would do her no good as a trust held the money, and it could not be released. She also claimed a soured ex-lover had made up the story to mess up her life.

The agents eventually discarded the case.

Interviewed by the Feds in June of 2000, Marshall Jr. said Anna had spent almost no time with her husband after their marriage, and that his father had often complained she demanded $50-60,000 in cash, at least once a week.

In 2006, the Supreme Court ruled that Anna could pursue her late husband’s fortune, and now her attorney and lover, Howard Stern, plus her mother and another boyfriend have been engaged ever since in a litigious war to each gain control of — and ATM access to – an estate that will go to Anna’s daughter, Dannielynn, who is now three-years old.

Anna herself died, alone and despairing at the Hard Rock Hotel in Hollywood, Florida on February 8th, 2007.
