Banks went to Heather Highlands mobile home park, where his former girlfriend Sharon Mazzillo and their son Kissamayu lived, of whom he had been trying to gain custody. Banks forced his way in and shot Mazzillo. He then shot and killed his sleeping son. Banks killed Sharon’s mother, who was trying to call police, and Sharon's 7-year-old nephew, who were also in the home. Hiding in the closet was Sharon’s brother, whom Banks did not see. He was the only survivor and called police, identifying Banks as the shooter.
