When he was busted last summer, he told police they should be arresting real criminals, not a good family man.

Now, illegal immigrant Adan Tanicio Guerrero has pleaded guilty to ID theft.

The county attorney says Guerrero was living in Mesa using a false Social Security number when he tried to buy a $33,000 truck.

Ironically, the credit union he applied for a loan at is the same one used by the victim of the stolen ID.

A credit report showed Guerrero had nearly $800,000 in loans under the victim's Social Security number.

He'll be sentenced next month.
