AURORA | A 17-year-old charged as an adult for his role in a 2021 shooting at Aurora’s Hinkley High School pleaded guilty Thursday to attempted second-degree murder, according to court records.

Larry Jefferson is one of three teen boys charged in connection with the shooting, which injured three students and sent others fleeing for their lives. Charges against a fourth teen were dropped in June 2022.

Other charges against Jefferson — including four counts of attempted first-degree murder and other, less serious crimes — were dropped. Jefferson was named publicly along with the other defendants due to the nature of the charges and the seriousness of the alleged crime.

Police have said the shooting was gang-related and that the alleged shooters were armed out of fear that they would be jumped by members of a rival gang.

Jefferson is scheduled to be sentenced April 4.
