A 14-year-old Therrell High School student is being charged with murder in the apparent stabbing death of his grandmother, police said.

Mary Price, the mother of an Atlanta Police officer, was found dead inside her home today after her grandson showed up at school wearing bloodied clothing.

"The subject went to school and made statements to authorities there," Atlanta Police homicide unit commander Capt. Paul Guerrucci said. "School resource officers questioned him because of his appearance."

The information the teen gave school officers led police to his home in the 1600 block of Fairburn Road in southwest Atlanta, where he lives with the 76-year-old Price, Guerrucci said.

Police found Price dead inside the home with multiple injuries that Guerrucci characterized as "most likely some kind of stab wounds."

It is unclear what the suspect told police officers who interviewed him, but Atlanta Public School officials suggested there had been some kind of dispute.

"A student from Therrell High School was involved in a domestic incident that occurred off-campus prior to the beginning of school this morning," APS spokeswoman Kimberly Willis Green told The Atlanta Journal-Constitution in an email.

The teen was arrested around 9:30 as officers left the school to check his home, but it is unclear at this time whether he will be charged as an adult.

Police are not saying just how the Therrell student is related to the officer who is Price's son.

Police have not identified the teen, and are still trying to determine whether he acted alone or if anyone else was home at the time of the incident.

An autopsy is scheduled for Saturday to determine the cause of Price's death.

The investigation is ongoing.
