Livingston County sheriff tweeted Thursday evening that Starrlita Smith had been found alive. He says she is being treated for dehydration and malnutrition. Smith, who has special needs went missing Monday evening. Deputies are not certain where Smith was this week after she just walked back into her home Thursday evening.

Deputies say they have located the 21-year-old woman missing in Livingston County.

Sheriff Tom Dougherty tweeted Thursday evening that Starrlita Smith had been found alive. He says she is "being treated for dehydration."

Smith, who deputies say has special needs, went missing Monday evening, leaving her home with just two blankets and a flashlight. Crews searched the area extensively over the last few days, but Smith was not located until Thursday night.

Speaking at a news conference, deputies say Smith's parent's called 911 around 8 p.m. after she "walked in from the garage."

Where has Smith been for the past three days? Deputies are still working to figure that out. Sheriff Dougherty says they are relatively sure she wasn't in the garage for that period of time. It was searched on different occasions with dogs. Earlier in the week, deputies also said a driver spotted someone matching Smith's description on Jones Bridge Road.

But, at the same time, the sheriff says the garage has a lot of items in it, and it's not impossible that she may have been in there. Smith could only tell her parents that she had been sleeping for the past three days.
