(Yahoo!) The Ontario County (N.Y.) Sheriff's Department's investigation into the death of Kevin Ward Jr. is complete and has been handed over to the Ontario County District Attorney.

The OCSD has been investigating the death of Ward for approximately a month after he was struck and killed by Tony Stewart on August 9 in a sprint car race at Canandaigua Motorsports Park. After missing three races, Stewart returned to the Sprint Cup Series at Atlanta Motor Speedway.

Any action against Stewart will be announced next week, according to the OCSD. When speaking during the early stages of the investigation, Ontario County Sheriff Philip Povero said there was no evidence of criminal intent in the incident.

The Ontario County Office of Sheriff has completed its' investigation into the death of Kevin A. Ward, Jr., which occurred August 9, 2014, at the Canandaigua, New York, Motorsports Park. The entire thorough investigation, including a forensic video enhancement recently received from the New York State Police Laboratory in Albany, has been submitted to the Office of the Ontario County District Attorney for review. The District Attorney’s Office, which has been meeting throughout the investigative process with members of the Sheriff’s Office, will make a statement late next week advising what action will be taken regarding the investigation.

Stewart and Ward were racing together August 9 when Ward's car hit the wall. After it came to a stop, Ward climbed from his vehicle and went down the track towards the rest of the field. As he gestured angrily at Stewart, the right rear tire of Stewart's car struck Ward, killing him.

A video of the accident surfaced on YouTube later that evening. Povero said the OCSD had obtained a second video during the investigation and it is unclear what footage the forensic video enhancement refers to.

Even though the incident didn't happen at a NASCAR-sanctioned race, NASCAR banned drivers from getting out of their cars before safety personnel arrive less than a week after Ward's death.

Stewart received a waiver from NASCAR to make the Chase for the Sprint Cup if he were to win at Atlanta or Richmond. He did not win either of those races, and is not in the Chase. Aside from a three-minute statement at Atlanta, Stewart has not commented publicly on the incident.
