Attempted murder
There is attempted murder (664/187), which is punishable by 5-7-9. Some, including Californian courts, have called this second-degree attempted murder.
There is also attempted murder, which is willful, deliberate, and premediated (664/187/189), which is 7-to-life. Some, including Californian courts, have called this first-degree attempted murder.
The California Supreme Court in People v. Bright (1996) 12 Cal.4th 652, has explicitly said there are no degrees of attempted murder, just an enhanced punishment for willful, deliberate, and premeditated attempted murder. This supposedly made a difference because the Court in Bright said a jury finds whether there has been attempted murder or not, and not the "degree" of attempted murder. But, the Court later said in People v. Seel (2004) 34 Cal.4th 535, Apprendi applies to this, so a jury does need to find a fact that increases the sentence, and thus a jury does need to determine if it's been willful, deliberate, and premeditated.
