What is the standard for determining that no rational trier of fact could have found a supplemental petition without a reasonable doubt?

3 We would reach the same conclusion following the standard set out in Jackson v. Virginia (1979) --- U.S. ----, 99 S.Ct. 2781, 60 L.Ed.2d ---. We would not conclude in the instant case that no rational trier of fact could have found true the allegations of the supplemental petition beyond a reasonable doubt. (See Jackson --- U.S. at p. ----, 99 S.Ct. 2781.)
