A warrant has been issued for the mother of an infant that was seriously injured this past month. In a release from the Vandalia Police Department, it says that Fayette County State’s Attorney Joshua Morrison had a warrant issued for the arrest of 23 year old Aubree L. Hammer of Vandalia for the offense of aggravated battery to a child under the age of 13 with great bodily harm or permanent disability. And, the charge is a Class X Felony. The release goes on to the state that the warrant charges that Aubree L. Hammer “knowingly caused great bodily harm and permanent disability to a child under the age of 13 years, in that she she held the child’s head high and threw him to a wooden floor causing brain damage.” The issuance of the warrant stems from the investigation that started on the afternoon of February 18th in Vandalia. The earlier release said that the child, who was 3.5 months old, was transported to Fayette County Hospital for treatment at that time. And because of the seriousness of the injuries to the child, the Vandalia Police Department activated the Child Death Investigation Task Force. The release states that Aubree L. Hammer is the mother of the injured child and the bail amount on the warrant is set at 1 million dollars. The release also adds that Vandalia Police Department, along with the Illinois Child Death Investigation Task Force will be conducting a follow up investigation until completion. The release did not state the child’s condition at this time.
