UPDATE: Estes’ sentencing was rescheduled to Jan. 14, according to court documents.

Zaria Estes, the 15-year-old girl responsible for attacking a Temple student with a brick in March, pled guilty to aggravated assault, conspiracy and possession of an instrument of crime on Tuesday morning, as was first reported by the Philadelphia Daily News.

The state is dropping three additional charges: making terroristic threats, simple assault, and reckless endangerment of another person.

According to Estes’ court docket, bail was set at $100,000 on April 18. She faces a maximum sentence of 10 to 20 years in prison for the lead charge of aggravated assault.

Estes was part of a group of girls who attacked four Temple students during a half-hour span on March 21. The brick incident happened in the 1700 block of Norris Street, and the victim needed oral surgery and suffered a mild concussion.

Two other girls involved were initially charged as adults, but the adult charges were later dropped after court proceedings.
