Police say they charged the man driving the ambulance, 22-year-old Justin Janaitis, of Norristown, with receiving stolen property and driving under the influence.
Police say it was not immediately clear why Janaitis had taken the ambulance.
I'm going to go out on a limb and suggest that the "under the influence" part might also provide the why.
Receiving stolen property seems like an odd charge. Anybody know if that's the same as possession of stolen property? That would make sense. If nobody actually saw him take the ambulance, the cops would fall back on the possession charge, which they can prove easily enough.
