This didn't happen in Houston, it happened in Sugarland, which is a small high class town (mostly bedroom community) in the next county, right next to SW Houston, and about 10 miles directly via US 59 - the Southwest Freeway, from the Enron building, where many of the pretty damn rich (as opposed to the super rich) live, who work in SW Houston.
I didn't say it happened in Houston.
I said the Harris County ME would issue the cause-of-death ruling.
