I wonder if he has a gun, maybe his parents have one. That would certainly delay his parents contacting the police. The last thing they would want is to have to tell the police that he is on the run with a gun.
Also, I'm surprised both Brian and his parents were able to leave apparently without being noticed and/or followed. He was featured in the news then and it just seems very strange that Brian was able to apparently set off for a hike in a car alone and unnoticed.
That would be easier though if the car was round the corner as opposed to being on the drive, or that he went at night, which further adds to the ridiculous description by his parents of what he was wearing when they saw him last.
