Torin Jacob Williams, 20, was living in a home in the 11000 block of Day Camp Lane in Austin when Round Rock narcotics and SWAT officers served a search warrant around 5:30 a.m. on Thursday, 20 December 2018.[1] Williams was arrested and charged with felony manufacturing of a controlled substance.[1] Court documents showed police found 311 grams (0.311 kg) of THC oil in the home.[1] Some of the oil was in individual cartridges called “Mario karts.”[1]

Neighbor Tina Nguyen said the police arrival woke her; officers used a megaphone outside the house, and she recalled, “We saw a bunch of police, we were like freaking out.”[1] Another neighbor, James Griffin, said he found it surprising that THC oil had been found in the neighborhood.[1] Griffin said cars would drive quickly into the cul-de-sac and turn around before driving out, a pattern he considered unusual.[1] Round Rock Police said they were noticing THC oil more often than before.[1]
