Authorities: 14-year-old stabbed grandmother more than 50 times

After allegedly stabbing his grandmother more than 50 times, a 14-year-old boy went to school, still covered in blood, investigators testified Thursday in court.

When Charles Price arrived at Therrell High School last Friday, his teachers initially thought the teen had killed another student, prosecutors said, according to Channel 2 Action News.

“I killed it,” Price allegedly said.

When investigators went to the southwest Atlanta home where Price lived with his grandmother, they found the woman's body inside and a gruesome scene, Atlanta police Detective Kevin Otts testified. Mary Price, 76, had been stabbed multiple times inside the Fairburn Road home, where the bloody crime scene spread from the kitchen to the living room, Otts said.

The April 18 stabbing may have followed an argument over the home’s television DVR, Otts told the courtroom.

Prosecutors confirmed in court that the teenager has been charged as an adult with killing Mary Price, the mother of an Atlanta police officer. The police officer is not the father of the suspect, police previously said.

Charles Price is being held without bond and is scheduled to return to court later this month, Channel 2 reported.
