WATCH: Slain Gun Instructor's Family Delivers Video Message To 9-Year-Old New Jersey Girl

The family of an Arizona gun instructor who was accidentally killed by a 9-year-old New Jersey girl using an Uzi submachine gun has delivered a video message (see below) to the girl, saying they’re praying for her and they “wish you peace.”

The video message was published by attorneys for the family of Charlie Vacca on the firm’s website.

In the video, Marc Lamber, attorney for the personal injury law firm Lamber/Goodnow of Arizona, talks about how it is important for Vacca’s children to share information about the father ”they knew and love” and to help bring closure to the tragedy.

“Now we intend to work cooperatively with authorities and investigative agencies to determine how this could have happened, and more importantly, how it could have been prevented,” Lamber said.

Vacca’s son, Christopher, starts the reading and, addressing the 9-year-old girl, says: “We don’t know your name but we are connected by this tragedy.” The other children appearing in the video are Ashley, Elizabeth and Tyler.

Vacca’s children praise their father as a “hero,” someone who was “funny” and a “protector.” Addressing the girl, Tyler says: ”Your are only 9 years old. We think about you. We are worried about you. We pray for you. And we wish you peace.”

Mohave County Sheriff Jim McCabe said no charges will be filed regarding the tragic shooting of 39-year-old gun instructor at the Arizona gun range. Last month, the Sheriff’s department released the heartbreaking 911 calls recording the desperate attempts to save the fatally-wounded gun man.
