In the Netherlands (the law of which Aruba follows), the maximum sentence for murder is 20 years. Yes, in rare occassions, a life sentence (not mandatory) may be given, but the circumstances must be extraordinary (multiple murders; prior convictions, etc.).
Some research on the Dutch punishment system shows that a typical murder sentence is about 15 years, shortened by about 1/4 for good behavior. Attempted murder gets you about 3 yrs.
Napolitano/Fox said yesterday that the defendant appears before a judge who asks all the questions of the defendant and two attorneys and makes the decision on punishment. No jury.
