Looking at Google Earth and a Reuters photo of the crash scene (the one with the Airport direction road sign) it would seem possible that they'd lined up with the airport access road which runs roughly parallel to runway 02 but about 400 metres right of it. The airport road is a residential area (houses on the right side of the road) so it will probably have good street lighting. Might explain why they had descended below minimums thinking they had the runway in sight.
