UPDATE: Bond is set at half-a-milion dollars for a DeKalb County, Alabama man who confessed to beating his mother to death.     Tyler Ryan Blansit told police he and his mother had been arguing over his grades.  


DEKALB COUNTY, AL (NBC News) - A 22-year-old student allegedly confessed that he killed his mother following an argument over his grades, officials said.

Tyler Ryan Blansit was arrested for murder in Mentone, Alabama, on Saturday, according to the DeKalb County Sheriff's Office. The suspect's mother, Sherry Ann Blansit, was found beaten to death behind her home on Friday, NBC affiliate WAFF reported.

Investigators say Blansit admitted to striking his mother in the head after the two clashed over his academic performance. It appears that Sherry Ann Blansit's death was caused by "blunt force trauma to the head area," the sheriff's office said.

Blansit is a student at the University of Alabama-Birmingham.

"Usually we'll have calls where a parent has whipped a child because of grades, a child has run away because of bad grades, but we've never had anything like this happen," Sheriff Jimmy Harris told WAFF.
