Dallas reporter Stacy Fawcett killed by teen son who suffered brain injury, police say

Popular Dallas food reporter Stacy Fawcett and her 17-year-old son are dead after police say they were attacked early Friday by Fawcett's eldest son, who then fatally stabbed himself.

Police say Fawcett, who regularly appeared on WFAA's weekend moing shows, and Josiah Utu were stabbed to death by 19-year-old McCann Utu Jr. The elder son stabbed himself at the scene and later died at a hospital, according to authorities.

McCann had reportedly been battling depression after suffering a traumatic brain injury several years ago.

"He had just completely mentally dwindled away," said Scott Fawcett, Stacy's brother.

McCann's uncle told KTVT that McCann's mental state changed after the injury. Neighbors said he would wander away from home and that his mother would ask for help looking for him.

His uncle says he thinks the young man's brain will show signs of chronic traumatic encephalopathy, a disease linked to brain trauma that can cause depression, behavioral changes and progressive dementia.
