One video shows the man now being scrutinized in the torture-murders of a wealthy D.C. family and their housekeeper.
Twenty-eight-year-old Jordan Wallace is a race car driver who was featured in a video for a go-kart track in Maryland.
In the video, he said, "Anything with four wheels and a steering wheel, I'm ready to go. I'm living the dream. I'm feeling pretty good about my situation."
That's where he first met 10-year-old Philip Savopoulos and his father, Savvas.

Wallace went to work as the businessman's driver/assistant in April after he was reportedly fired from his job at the racetrack.
Cops reveal it was Wallace who was asked by Savopoulos to drop off $40,000 in cash at the mansion in Washington D.C. Hours later, the house was set on fire.
Investigative journalist Nate Thayer says there's a connection between Wallace and Daron Wint, who's been charged in the murders. Police are searching for possible accomplices.
INSIDE EDITION's Les Trent asked Thayer during an interview, "What is the link between Jordan Wallace and Daron Dylon Wint?"
Thayer said, "Jordan Wallace and Daron Wint grew up in the exact same apartment complex over a number of years. These apartments were literally within feet of each other."
Jordan Wallace has not been charged with any crime. Wint was arrested after his DNA was reportedly found on the crust of a Dominos pizza left behind at the mansion.

Now, cops are revealing new evidence against Wint, including blood on his shoe when he was arrested that matches one of the victims.
Wint's attorney is Robin Ficker. He told INSIDE EDITION, "I don't believe them when they say there were little specs of blood on his shoe, and I predict that when the trial comes, they won't introduce such evidence."
Ficker has become a national figure with what some see as his over-the-top statements regarding the case.
Turns out, Ficker is the same guy who, back in the 1990's, was notorious for heckling NBA legends like Charles Barkley and Michael Jordan.
Ficker was a passionate basketball fan.
He told INSIDE EDITION, "I wasn't a heckler, I was a therapist. I was trying to suggest ways for these highly-paid, highly-stressed young men and their coaches, who had a short half-life to improve their play. I was trying to help them."
Now, he's back in the spotlight with the murder-mystery that's shocking the nation.
