MT. VERNON (WMIX) – A 16-year-old Mt. Vernon girl was shot and killed Saturday afternoon and a 16-year-old boy was arrested on charges accusing him of her shooting death.

According to the Mt. Vernon Police Department, around 4 p.m. Saturday, their Dispatch Center received a 9-1-1 call from someone screaming but giving no information about what was happening.

Officers were dispatched to the home in the 1800 block of Lamar where they found a 16-year-old resident had been shot. They also found a 16-year-old boy holding a handgun at the scene.

Officers were able to take the boy into custody and secure the firearm. Medical personnel from the Mt. Vernon Fire Department and Litton’s Ambulance Service were also dispatched to the scene.

The girl was transported to a local hospital where she was ultimately pronounced dead.

The boy was transported to the Mt. Vernon Police Department for processing.

He’s being detained on preliminary charges of Armed Violence/Discharge a Firearm, Aggravated Battery with a Firearm, Involuntary Manslaughter, and Unlawful Possession of a Firearm by a Person under 18.

Police say the State’s Attorney’s Office may amend those charges as the investigation progresses.

The Mt. Vernon Police Department reports they had previously arrested the 16-year-old boy at the end of April 2023, after an MVPD dispatcher saw him with a handgun and notified officers.

The boy reportedly fled from officers but was ultimately apprehended following a foot pursuit.

Officers then reportedly found a loaded firearm and additional ammunition in his possession, and he was taken to a juvenile detention facility on charges of Armed Violence, Aggravated Unlawful Use of a Weapon, and Resisting Arrest.

At the time of his Saturday arrest, the 16-year-old boy was on parole and the Illinois Department of Corrections was notified of the latest arrest.

Before the arrest in April of 2023, the boy had been arrested by the Mt. Vernon Police Department for Armed Robbery in one incident and Aggravated Battery in a separate incident.

His name is being withheld due to his age.
