A 24-year-old woman who has the mental capacity of a 15-year-old has been missing for a week, and friends and family members are concerned. Actor David Hasselhoff weighed in, tweeting, “A friend of mine's sister is missing. She was last seen in Downtown LA. If you are in LA please re-tweet this.”

They say Tanya Fielding went missing from her downtown apartment last Tuesday and “needs her meds” because she has epilepsy.

She was last seen …

… roaming Hollywood Boulevard, with a street performer telling CBS2 (via Weho Daily) that she reported she was mugged and had to sleep under a freeway overpass.

She's described as 5 feet, 2 inches tall, 115 pounds, with a scars on her forehead and the back of her neck.
