DEMOLISHING HOUSTON’S GRISLY PAST “Houstonians just don’t celebrate death and the past the way New Orleanians do,” writes John Nova Lomax in his recounting of 4 creepy tales from Bayou City history. “In fact, we tend to simply forget all the awful and weird things that have happened here over the last 176 years, and mercifully so, because there have been an enormous number of terrible episodes.” It’s much easier to forget, of course, when the gruesome settings themselves are summarily disposed of. The “Houston Heights House of Horror” — a 3-room shack at 732 Ashland St. that was the scene of a noted hatcheting in 1910 — by 1937 had been torn down and replaced. Its substitute is gone now too; a warehouse that’s home to a company called SemaSys now stands in its place. And down in Seabrook, condos occupy the site of the famous warehouse-like “Mansion on Todville Rd.” (in photo) where in 1984 a group of housesitting youngsters murdered its owner, child predator Bill List.
