Tony Clifford

was an orderly at Idlewood. In episode 3x00 "On Faith," we saw Clemson McCain kill Clifford on October 17, 1995, at the end of an interview with Solomon Todd. 

In the original airing of the DVD extra "Self Defense", Stephen Reyes stated:
 * Currey's death, and the subsequent death of orderly Tony Clifford, prompted a complete overhaul of the management, training, and security at Idlewood.

Emma Bull later noted that the word "subsequent" was incorrect and should have been "previous", which makes sense given that McCain killed Clifford in 1995 while Currey died occurred in 2002.
