More than 20 people - including a veteran Houston police officer - have died or are feared dead in the Houston area in flooding triggered by Tropical Storm Harvey, according to local officials. Among those is a family of six reported missing after their van was overtaken by floodwaters in east Houston Sunday afternoon near Greens Bayou. Their bodies have not been recovered. Medical examiners are in the process of confirming which deaths are related to the storm, which has brought as much as 47 inches of rain to some parts of the Houston area. And authorities are still searching for some of those believed to have perished during the flooding that has overwhelmed the region.
