All cars are required these days to have a built in boot release, the Camry has one, but you would need to access the boot, some have folding seats (released from the boot ) so I would attempt to cut through a seat back of rip it fwd then access the release, even 9nce in the boot you could access tools the break a window.... the other would be to tear the door card off and gain access to the lock or the window mechanism.... poor sod, it must have been a nightmare.
