On April 3, 1995, Derek Harrison, a 35-year-old man from Corpus Christi, Texas, tragically lost his life in a mass shooting at the Walter Rossler Co., a refinery inspection firm. The incident occurred when James Simpson, a former employee of the company, walked into the office and methodically shot five people, including Harrison, before taking his own life. The other victims were Walter Rossler , his wife Joann Rossler , Wendy Gilmore , and Richard Tomlinson .
The motive behind the shooting remains unknown to this day. Simpson had left the company seven months prior to the incident, but authorities have not determined why he did so or what prompted the attack. The shooting was one of the bloodiest crimes in Corpus Christi's history and occurred just days after the murder of Tejano music star Selena Quintanilla, adding to the city's grief.
Despite extensive investigations, no arrests or suspects were identified in connection with Harrison's death, as Simpson was the only person involved and he died at the scene. There were no litigations or law cases related to the incident, as it was treated as a tragic act of violence with no clear motive.
The community of Corpus Christi was deeply affected by the loss of Harrison and the other victims, and the incident remains a somber chapter in the city's history.
