(Portland, OR)  --  A woman was found guilty last week by a Multnomah County jury of starving and withholding medical attention from a child.  Thirty-eight-year-old Jamie Strahm dated the child's father and took care of the boy for several years.  He suffered an unexplained brain injury and was required to use a feeding tube.  Over four years the boy lost ten percent of his body weight.  At a hospital, the boy started eating by mouth and gained ten pounds over a month.  Strahm will be sentenced later this month.
