What are my rights as the victim of a juvenile offender? The family was promised a say in the proceedings but was never notified

My friend's son (17) was accidentally shot and killed in a home where 6 teenagers gathered after school to go jogging as they were all interested in the national guard. The father was rarely home to supervise when the teens were there and it was common to have several different firearms available to them. The friend who shot him was also 17 at the time. After an investigation,the case was closed without any notice to the victim's family. They found out 3 weeks later that it had been closed by a memeber of the shooter's family and the sentence was a week in juvie, 42 hours community service and 1 yr probabtion
The prosecutor basically refuses to talk with the victims family, as no answers were ever given concerning the investigation.
