Does a party seeking to inherit a deceased's estate have any rights to share in the estate if they are convicted of manslaughter?

The rule set forth in Riggs v. Palmer has been expanded to those instances where the party seeking to inherit has been convicted of manslaughter with regard to the decedent's death (see e.g., Matter of Mazzella, NYLJ, Oct. 27, 2006, at 21, col 5 [respondent forfeited any rights to share in decedent's estate as a result of his conviction of manslaughter of decedent] ). In Matter of Timpano (40 Misc.3d 1237[A], 2013 N.Y. Slip Op 51472[U], *8 [Sur Ct, Oneida County] ), the court recognized that the forfeiture doctrine set forth in Riggs v. Palmer has been expanded to apply to a party who sought to benefit from decedent's estate but recklessly caused said death, citing Matter of Sparks (172 Misc. 642 [1939] [first-degree manslaughter] ) and Matter of Wells (76 Misc.2d 458 [1973] [second-degree manslaughter] ).
