I heard they found OJ Simpson by his cell phone. Apparently cell phones
communicate every few seconds with the network, even when just in the
on/standby mode, so the network always knows which cell site the phone
is closest too. They saw his phone moving from cell site to cell site
located along a freeway, giving john law a good general area to focus
on....
