I heard of that same problem in another location too. I just can't remember where.We were on holiday in Crete in 2004 when we came across some locals who were combing the beach looking for hatchlings. They have confused by the lights of the hotels and instead of heading to the ocean they have been heading in the wrong direction so we just put them back in the sea. There is obviously a problem with turtles and light pollution in Crete.

These people were from a local wildlife sanctuary/charity.I heard of that same problem in another location too. I just can't remember where.
The top picture is a sea turtle and needs to be put in the ocean. It's against the law to mess with them.
The others look like sulcata, but need better pictures to be sure.
