Need an ID please

While rustling paperwhites and jonquils on vacant lots in town I found these. They look just like mini crinums to me. I find lots of crinums but they are always several big bulbs with maybe a few small offsets. These all seem very uniform. They have the plastic-like, robust foliage like crinums but they don't seem to want to fall over. Granted they just came up and are only a foot tall but I would expect them to flop a little if they were crinums. The tips have a neat little twist on them.
I'll keep them in the greenhouse since they seem to want to grow right now and see what happens. Does anyone have any ideas?

I think we will need to wait and see a bloom to be sure what it is.

They look like Crinum lilies to me.
