(CNN) The shooting at a congressional baseball practice in June and the methods of the gunman behind it are described in the starkest detail yet in a report released Friday by Virginia officials.

James Hodgkinson, the 66-year-old shooter, had taken cellphone video of the field where the Republican team practiced as far back as April, and had been spotted by neighbors “casing” the area in the months preceding the attack, according to the report, written by the commonwealth’s attorney for the City of Alexandria.

One member of the baseball team remembered seeing Hodgkinson sitting in the stands of Simpson Field and watching the team practice the morning before the incident, the report reveals.
