After the family left the rented home earlier this year, they purchased a new home in late April and the teen resumed his experiments, Ray said.
The teen had moved barrels containing chemicals to the backyard to make room in the house for his mother and sister, who attends college on the East Coast, Ray said.
“A neighbor might have seen those barrels and smelled something,” Ray said. “And now we’re literally back at square one.”
The teen, who was a juvenile when law enforcement first visited the family earlier this year, was never charged, Ray said.
“We anticipate no charges in this incident,” Ray said. “He’s an 18- year-old trying to find a cure for cancer.”
