On July 23, 2011, 21-year-old Hien Ta of Grand Prairie, Texas, was killed during a mass shooting at Forum Roller World. Ta, an AT&T repairman and active member of Sacred Heart of Mary Catholic Church and Vietnamese Martyrs Roman Catholic Church in Arlington, was attending his brother’s birthday party when gunfire erupted.

The shooter, identified in reports as the estranged brother-in-law of one of the attendees, also killed several members of the extended family and injured four others. Court records cited in accounts show a history of abuse and threats involving the shooter and his wife; she had filed for divorce and a protective order but later withdrew those requests.

The Grand Prairie Police Department investigated the incident and did not identify any additional suspects. If anyone attended the party or knew Hien Ta and his family, did you notice anything unusual before that evening?
