FARMINGTON, PA -- A Pennsylvania woman has been charged with endangering her 11-month-old son by restricting him to a vegan diet of only fruits and nuts.State police say 30-year-old Elizabeth Hawk, of Farmington, became "obsessed" with the vegan diet, which prompted her estranged husband to contact Fayette County child welfare workers.A police complaint says the baby developed a rash "so bad that the child was scratching his skin off." Hawk allegedly refused to use a cream to treat the rash.Online court records don't list an attorney for Hawk and she doesn't have a listed phone. She's been mailed a summons for the child endangerment charge and faces a preliminary hearing Nov. 14.Police say doctors determined in August that the baby is developmentally disabled and can't crawl because he's malnourished.
