Kate was an LA cop who reluctantly helped Angel even after finding out what he was. Although she was drawn to him, Kate fought any impluse to like or help him
because her father, also a police officer, was killed under suspicious c
ircumstances, possibly by a vampire. When last seen (near the end of S2), Kate had had something of
a breakdown, lost her shield, and tried to commit suicide; Angel saved her.  She left town, and hasn't been seen since.
