JJ. I'm no expert but we go grow a bunch of evergreen trees up this way.
I was thinking it was some kind of Thuja/arborvitae. Has it been very cold in your area? If so some of these will brown out but turn green again by summer. Just wait and see if you get new growth this growing season. Also it could very well be dead but it cost nothing to wait. There are evergreens that turn brown, pruple or yellow in the cold of winter but then green out in summer. They are doing amazing things with evergreens these days.

This is what I was talking about. Winter burn.
