Charles Manson's still on ice, but the battle's heating up for his body -- and the 3 lucky finalists in line for the corpse all have some issues, which have now fallen in a judge's lap.
According to docs, obtained by TMZ and filed by the Kern County Coroner, 3 men are claiming Manson's bod. The first is Michael Channels, who submitted the first will from Manson -- but it's only partially legible. Plus, Channels is listed as a witness, which casts doubt on the will's validity.
Contestant #2 is Matthew Robert Lentz, who claims to be Manson's son and also filed a will, but his only has 1 witness -- at least 2 are required -- so it's incomplete.
Last up ... Jason Freeman -- who says he's Manson's grandson -- filed legal docs to prove he's Charles Manson Jr.'s son ... seemingly making him the murderer's next of kin. The problem here is, before his death, Manson told prison officials he had no family.
In other words ... it's legal helter skelter. Good luck sorting it out, your honor!
