According to her SimDNA in SimPE, Susan's hair was blonde before it turned grey. According to her age data, she had 11 days left in the elderlife stage when she died. Like most pre-made deceased Sims from The Sims 2, Susan is completely unplayable without the use of hacks or third party programs, such as SimPE.
Though her character data was deleted, regenerating her with SimPE is a tad easier than most dead ancestors, as her facial features are almost, if not identical to that of the 22nd Maxis face template in Create a Sim, unlike most "unresurrectable" Sims that have customized facial features.
This Sim has no character data and cannot be resurrected in-game. For more information, read this guide.
