Close Browser Tab with VB

Is there a way to close an IE browser tab with VB? I've searched for hours and feel I'm missing something simple.

Here's the basic idea:

I'm importing data into Excel from web pages that also have links to pages that contain additional (detail) data. I open IE and navigate to a page, find the link, open a second tab... but after I access that second tab, I need to close it.

Here's some of the code I'm using -- everything works as expected until I need to close the second tab:

Code:

---

Sub MainProcess()
' Note that I have enabled references to the Microsoft HTML Object Library and Microsoft Internet Controls
    Dim IE As SHDocVw.InternetExplorer
    IE.Navigate URL
    ' some code to get the first batch of data I need and find the links to the additional data
    wbOpenNewTab detailLink ' where detailLink is defined above
End Sub

Private Sub wbOpenNewTab(URL)
    IE.Navigate2 URL, 1
    ' This is where I copy the data I need
    IE.Quit ' This incorrectly closes the first tab, not the one I just opened
End Sub

Any help is appreciated.

it would be possible to loop through the shell windows, to find the appropriate one, based on some criteria (eg. the url), and close it
