OK - I found this:
To assist probation officers and parole officers with their supervision and to aid in the general law enforcement need to curb recidivism, many states require parolees and probationers to agree that their conditional release will be subject to curtailment of their normal Fourth Amendment protections. Typically, the released convict agrees to submit his person, property, and residence to warrantless, suspicionless search and seizure by any correctional or law enforcement officer for the duration of the probationary or parole term.
SO if there was a probation violation at the time — will this probationer get charged under the “felony murder rule”?
