(a) After all right to appeal has been exhausted, a judgment of conviction establishing criminal accountability for the felonious and intentional killing of a decedent:
(1) Is admissible in a civil proceeding in which the common law Slayer’s Rule is raised as an issue; and
(2) Conclusively establishes that the convicted individual feloniously and intentionally killed the decedent.
(b) This section may not be construed to prohibit a trier of fact, in the absence of a criminal conviction, from determining by a preponderance of the evidence in a civil proceeding that a killing was felonious and intentional.
