Attempting to cover up the shooting, the parents made the children, including Shariya, walk half a mile away to claim it was the result of a drive-by. Probably because the step-father had a criminal record that included firearms charges.
From a write-up at the Ohh Shoot blog:
7-year-old Shariya Jackson, of Cincinnati, Ohio was shot in the back while playing with a gun with her 3-year-old brother. The children found the loaded, unlocked handgun on their parent's bed. It had been left there by Ricky Singleton, their step-father.
After the shooting Singleton and the girl's mother, Tangie Jackson, attempted to cover up the incident. They hid the gun in a closet and made their children, including the injured Shariya, walk half a mile away from their home before calling the police. They originally told police Shariya was injured in a drive-by shooting. But police didn't buy the story.
Shariya was taken to the hospital with non-life-threatening injuries and Singleton and Jackson were arrested and charged with tampering with evidence, endangering children and obstructing official business. Singleton has a lengthy criminal record, including previous firearm charges.(A related news article)

Every gun in the hands of a child must first pass through the hands of an adult.
