More than a century ago, one of the earliest-known American serial killers chose the sleepy city of Austin to wreak havoc, brutally murdering eight women with an axe. He was never caught.

For a full year, the "Servant Girl Annihilator" terrorized the town, attacking along the streets we now know as downtown Austin. 

One tour group, Walking Tours of Austin, is sharing the story of this "midnight assassin," leading ticketholders on a tour nearly two hours long covering two miles of downtown, throughout Sixth Street and the Warehouse District, including a stop at the Driskill Hotel (which has ghost stories of its own).

Tickets are $40 per person, and it's an adults-only tour (age 13 and up). The tours start Oct. 3 and run every Thursday, Friday and Saturday night in October (excluding Halloween, unfortunately), and every Friday and Saturday night in November.

If the Servant Girl Annihilator tour isn't your thing, the group offers a 75- to 90-minute ghost tour for $20 per person (or $10 for kids 10 and under), and tickets are available most nights in October, November and December.
