A 22-year-old man is scheduled to appear in court on Friday to answer to charges in connection with the shooting death of a 12-year-old boy in Boston.

Walter Hendrick will be arraigned in Dorchester Municipal Court on charges of improper storage of a firearm potentially accessible to someone under the age of 18; unlawful possession of a firearm; and unlawful possession of ammunition, Boston police said in a statement.

It could not immediately be determined if Hendrick had an attorney who could respond to the allegations.

Mayor Michelle Wu said first responders attempted to resuscitate the child.

"It’s a horrible tragedy for the entire city whenever anyone of our young people is lost, and for a child of this age being lost to gun violence is a nightmare," she said in a news conference at the scene Thursday. "In the summer when our kids should be enjoying, having fun, playing and growing, this is especially a nightmare for a mom and for a family."

Police Commissioner Michael Cox called the death unnecessary.

"I implore folks, if you have guns in your home ... turn them in to us," he said.
