What is the test for determining whether sufficient evidence exists to convict defendant Has of manslaughter?

In determining whether sufficient evidence exists to support a jury's verdict, we must determine whether, "after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt." Jackson v. Virginia 443 U.S. 307, 319 (1979) (emphasis in original). Based on our independent review of the evidence, we conclude that sufficient evidence existed for a reasonable jury to find Has guilty of manslaughter.
