need to remove duplicates based on key in first column and pattern in last column

Given a file such as this I need to remove the duplicates.

Code:
00060011    PAUL BOWSTEIN          ad_waq3_921_20100826_010517.txt
00060011    PAUL BOWSTEIN          ad_waq3_921_20100827_010528.txt

  • The key is the first column.
  • The last column determines which record to keep, that is delete all other duplicates and only keep that one. The last column with the greatest date and time should be kept as shown in bold.
