Strange. All dudes.
yeah, usually its all women who get murdered....
Probably not a serial killer, but it is pretty common for people (often guys) to get drugged and robbed while drinking in Austin. Girl will offer a drink or shot spiked with scopolamine or GHB or Rohypnol. Guy, thinking with his second brain, takes drink from stranger, starts to lose his senses and is led to a car, then to the ATM, then to their home where they are thoroughly robbed, including bank transfers. I’d guess some guys notice themselves losing control and try to get out of the situation, and end up falling in the lake (or possibly pushed by an accomplice). So more like serial robberies with murderous side effects.
