My question involves criminal law for the state of: CA ( Tulare County )

my question is this with info:

my sister been getting Food Stamps and possible WIC since 2013 & 2014 & still into 2015 as of now, not sure how long into 2013 but she told me she took some time apart from her husband for 8 months but they was still paying her bills and giving her money from his work check.

she collects about $500 in Food Stamps + Cash Aid i think over $200, really not sure about the WIC, any way, her husband making making over $2,000 or more at his work every month and they got back together in fact we all got a place together and sharing bills.

if she lies to Food Stamps that they are still split up and using a PO BOX to get her mail and providing false into to get this money + going to Colllege and colletion free money over $1,000 ever so ofter and i dont think she is reporting it is this all farud or is it not a lot of info to report?

She also has 2 kids.

is this farud?.... should i report it and have it looked into? what will most likly happen to her?

UPDATE: She just got a Job, + Goes to School and gets Free Money called AID, + money from her husband that is living with her. + still collects food stamps and living with another family member to help cut costs! we are all on a rental lease
