The Challenger has to be just a potential witness and nothing more surely? You'd have to be an absolute moron to go and do a home invasion/abduction in an orange car that sticks out like a sore thumb. They're also very loud compared to normal cars. My boss drives a similar sort of thing and if he parks near the doors you can feel the vibration inside the building when he starts it up in the car park.
As for the Daily Mail they should be ignored completely. As someone in the UK I'm well aware of what a joke they are and they're the most dishonest paper in the entire country as per upheld complaints by the press regulator in regards to reporting inaccuracies and lies.
I guess an American comparison would be something like Fox News, where they just literally make things up to suit their agenda.
