That would give the state a case for premeditated murder, given they had known eachother and it’s something she could have pondered and planned. There’s no way these numbers are accurate on their face. 56 years for 1st degree murder is excessive for a minor. But the penalty should still be death. Judges don’t give a pass to vigilantes
Here’s an example of another young white man let off with probation not in California. Across the entire nation, according to the United States Sentencing Commission, the average sentence for abusive sexual contact is 5 years (60 months). An actual battery charge can carry a sentence of 14 years. Notice the difference? But more generally I’m talking about people who rape women & never even get convicted.
