A battle has erupted over the remains of cult leader Charles Manson. Only days after Manson died, three people have come forward as the main beneficiary to his estate. Manson’s self-proclaimed “son” Matthew Roberts is reportedly included in Manson's will, according to NY Daily News. TMZ.com obtained another will from Feb. 2002 that disinherits all of the Manson relatives. Manson died at the age of 83 due to natural causes.
