Staci Altman was a babysitter.
Season 11 Edit
Staci worked as a babysitter for the Harpers. At some point, she began having an affair with Dan Harper.
Staci wanted to share a life with Dan, but Dan was reluctant to divorce his wife because it was Valentine's Day. The two shared a kiss before Dan left for dinner with Melissa.
Staci was watching television in the living room when suddenly, "Dan" appeared from behind her. Staci was happy to see him, but was punched through the chest and left for dead on the sofa. "Dan" casually walked away with her heart. The incident was captured by the nanny cam.
