Did Johnny know his abductor

I’ve always heard about Johnny talking to a stranger, but what if it was someone Johnny knew? That would explain why there was no scream or ruckus. Say it was someone from the newspaper, they could have told him to leave his newspapers, someone else was going to pick them up. He would have gotten into the car willingly. It would have all gone smoothly, Johnny not putting up a fight. Of course there’s the issue of leaving his dog, but still, if it was someone he knew, someone he felt safe with, perhaps he would get into the car willingly.

Has the possibility of Johnny getting into a car owned by someone he knew ever been theorized?
