Associated Press/Dallas Morning News, Dec. 15, 2006http://www.dallasnews.com/sharedcontent/dws/news/texassouthwest/stories/DN-bpplant_15tex.ART.State.Edition1.3dcece9.html GALVESTON – Anger and frustration still linger for Roger Rodriguez about his son's death at the BP PLC refinery explosion. On Thursday, those feelings were mixed with gratitude and hope after the 15 people killed in the Texas City explosion were honored with a $12.5 million donation to the hospital burn unit that treated the most critically injured by the blast.  The donation by BP to the University of Texas Medical Branch in Galveston was part of a settlement between the London-based oil company and the daughter of two workers killed in the blast, which also injured 170 people.
