In 1885, Austin, Texas was terrorized by a serial killer known as the Servant Girl Annihilator. The murderer was never actually found, but he claimed eight victims, mostly black servant girls, all attacked in the dark of night. The very, very dark night of Austin in 1885.
Back then, once night fell, Austin had only moonlight. The city had no outdoor lighting until 1894, when Austin decided to buy more moonlight, in the form of towers. They were fifteen stories tall, each crowned with a circle of six lights, soaring way up above the city.
