rape and murder prison sentences in france

[blockatiel]

I thought this would be a lot more easier to find, but nothing I type in seems to work. My Google-Fu is weak.

What's the punishment in present-day Paris, France for child molestation/rape? I know sentences vary, so I'll say there are at least five victims.

Alternatively, what's the punishment for murder? One victim.

And can someone from the United States send a letter to someone in a French prison?
