Maybe you already know Google and Apple can use your cell phone to track your every movement.

Some of you may consider that creepy, but it's what helped us re-unite a confused grandpa from Illinois with the $10,000 Lexus he'd lost in D.C. after forgetting where he parked.

It was a happy ending to an incredibly frustrating story for Leonard Faircloth, 71, a handyman from near Chicago, his wife Evelyn, and his granddaughter Jaeleen, 9.

"Oh my God! I was just crying," said Evelyn. "People at work were clapping."

We found his new-to-him Lexus RX350 in the parking garage near the White House where he left it on the Fourth of July. It was only when he pulled out his claim check that he realized it didn't include the address for the parking garage. He had spent three days wandering around D.C. looking for the garage and the car and finally gave up and flew home without it.

His wife reached out to WUSA9, and we suggested she look for records of his movements on his Android phone. She'd never heard the phone might be keeping track.

"Thank God! No idea. Instead of timeline, I would name it lifeline. Now we can move on with our lives," she said.

The phone put his last location while driving on July 4 at 801 17th St. NW. There's a Nation Parking garage there. When she called them, they found the car.

Because Faircloth is a veteran, and because he forgot where he parked, the garage is actually going to waive the parking fee, which for a week is a lot of money. But there's a ticket from D.C. on the vehicle for $250. And he may have to pay that.

Faircloth plans to fly in Friday to get his car back. The family is hoping D.C. will cut them some slack and waive that $250 ticket.
