It's an AP article so I can't link and copy it here.
A Department of Public Safety officer made a traffic stop of a stolen pikcup truck suspected of carrying illegal immigrants north of Casa Grande this afternoon - near the Sacaton rest stop along west bound Interstate 10. Casa Grande is near where the Sheriff Deputy was shot earlier this year and near where two illegals used a cell phone to call for help but were dead by the time they were found - that was a likely case of one cartel attacking another.
A scuffle ensued and the patrol car was stolen. The driver later abandoned the patrol car 30 miles south of Phoenix. The driver was arrested. Strange. They don't report his immigration status.
