Looks like it could be a Trek frame, it has the wishbone seat stays and a 22mm disc brake mount on the chain stay.
The 22mm disc mount puts it in the late 1990's to early 2000's
The paint looks to be new as does the TREK decals on the down tube.
New decals can be bought:

The lack of a decal with the model number is a good indication that it's new paint.
Components on the bike can be changed so they aren't always a good way of telling what year it is.
