Also manslaughter in LA is a little different than most states. It's not really 'negligent homicide" its basically 2nd degree murder - you killed someone in the act of another crime or without specific intent to kil.. 2nd degree murder in LA is basically 1st degree everywhere else - you intended to kill someone and did.
1st degree murder in LA is intentional with an aggravating factor (killed a cop, multiple victims, etc)
