Petty Theft, What Do I Do Next

[PhilYancey]

My question involves criminal law for the state of: California, Orange County

Background:
My friend was charged with petty theft at a store. (We'll call it Store 2)
However, my friend was caught stealing at another store (We'll call it Store 1) previously and the store only sent a civil demand letter and did not involve the police.

When my friend was caught stealing at Store 2 (for a couple items under $10) the police officer was looking through my friend's purse and found the civil demand letter and read it. The police officer/station let my friend go after processing, but did not give any information on what will happen next.

Questions:
1: If the police officer found and read the civil demand letter, will the theft at Store 1 be considered the first offense, and the theft at Store 2 be considered the second offense?
2: Will they send something via mail informing my friend on what to do next? (statement of crime, court date, etc.)

Thank You!

I'm sorry I forgot to add one more detail:
My friend is over the age of 18

Oh dear.

Your friend needs an attorney.

If the police were involved, your friend will be getting a summons to show up for court. If the officer testifies that he found a civil demand from Store 1 when he arrested her for stealing in Store 2? It could really get ugly.
