Yes it is possible. You may need to consult with a Los Angeles attorney as well as one up in Santa Clara to deal with the violation of probation depending on what happens with the theft case. The LA case with formal probation sounds like a felony but you do not say. Good luck.
Yes it's possible. The petty theft is a crime which usually results in bench probation but this new case is obviously a violation of his probation in LA. Depending on what he's on probation for in LA and his prior record, this could be a very serious matter. Hopefully his attorney is handling both matters in a coordinated way. If he doesn't have an attorney he should hire one immediately. Good luck
