The kitchen and living were separated by a half wall. I removed it. Now I want to remove the remaining wall if it isnt load bearing. There looks to be a header, but the box sounds hollow.
I went to the attic and snapped a pic of what is happening up there. There just seems to be one lonely 2x4 coming straight down from the roof onto that wall

 

Does the wall run in the direction of the red line or the yellow line:

The yellow. The front slanted 2x4 is on another wall. The far 2x4 is the one I'm worried about.

 

I'm having a hard time orientating my view in the attic.
I don't see the register with arrow below near end of wall in attic.

Regardless, I would never say 100% you can remove a wall.
Looks like odds are in your favor. When a wall runs parallel to joists, it is normally not load bearing. You do have roof purloins and that could be an issue.

I'd consider removing only lower part of wall (yellow).
Run a header or beam across where wall is now. You would have to repair gap in ceiling anyway where wall was removed. May as well fill that gap with a beam.

You'll get more advice. There's some guys here very good at this.

The green line is where the part of the wall that still stands.
It looks like there is a support running to the roof. But just one.
The red line is wall that is staying.

 

OK,
So in my attic picture above, yellow line is pretty much the wall.

I'm sticking with the beam or double header idea (wall to wall). It does things to your advantage:

- Gets rid of wall
- No engineering required
- Saves repairing gap at ceiling
- Header could have decorative finish applied, and size would not be obtrusive

I'd wait for a few more opinions.
