Anna Nicole Smith Investigated by FBI in Plot to Kill Stepson

Wow talk about shady! Before Anna Nicole Smith died she was under investigation by the FBI because they believed she was part of a plot to kill her tycoon husband's son, whom she was battling for his late dad's fortune.

According to Popeater, the bureau investigated Anna in 2000 and 2001 in a murder-for-hire plot targeting E. Pierce Marshall, who was trying to keep his fathers money away from Anna Nicole.

"Smith adamantly denied ever contemplating such a crime," an agent wrote, and prosecutors eventually agreed the case could not go forward.

An April 26, 2001, letter to the FBI from Sally Meloch, an assistant U.S. attorney, said she reviewed the reports but "determined that there is insufficient evidence to establish that there was a murder-for-hire plot by Ms. Smith to kill Pierce Marshall."

The case against Anna was eventually dropped because there wasn't enough evidence to charge her. She died in 2007 from a drug overdose and E. Pierce Marshall passed away in 2006.

Of course the attorney for Anna's estate claims he doesn't know anything about the case. Do you think Anna was guilty of the claims? Tell us your thoughts!
