After all right to appeal has been exhausted, a judgment of conviction establishing criminal accountability for the felonious and intentional killing of a decedent: Is admissible in a civil proceeding in which the common law Slayer’s Rule is raised as an issue; and Conclusively establishes that the convicted individual feloniously and intentionally killed the decedent. 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.
