A vigil and silent march is scheduled today for 5-year-old Kaiya Kapahu, a special-needs child from Hawai'i who died in Arizona last month while in the care of her uncle.

Kaiya had Rett syndrome, a developmental disorder that left her unable to speak or perform basic motor skills, and required constant care.

Phoenix police say her uncle, Leonard Orta Jr., deprived her of food and medication and concealed her body in his apartment for at least a month after she died. Orta has been charged with first-degree murder, child abuse and concealment of a body.

Today's vigil and march will begin at 5:30 p.m. at the rotunda of the state Capitol.
