At 19, she's being charged in adult court, not as a minor.
Can you rephrase your question using normal sentence structure? Saying things like "it was discovered the parole officer was never contacted and was able to avoid the second MIP charge and just had her probation extended" does not make your meaning clear.
Do you expect an officer to have ESP? Why would an officer have to figure out if somebody is on probation, track down their probation officer, and report every possible new offense? If the probation officer wants to check to see if a probationer is charged with any new offenses, he can pull that up by computer. It's the probationer's duty to inform the probation officer of any new encounters with law enforcement.
