“The good part about (the process) is that it doesn’t use the toxic chemicals that meth labs do,” he said.

Austin, the woman and a 19-month-old girl were all injured in the explosion. Austin suffered from second-degree burns and the woman and baby suffered from first-degree burns, Brodie said. It’s unknown if the child is related to either of the adults.

Child Protective Services has been notified about the incident.

It’s also unknown if the injured woman is a student at the university, although UM said a female student resided in the apartment. Austin isn’t listed in UM’s online student directory.

The blast blew out three windows in the apartment, the screens on the bedroom windows in neighboring apartments, and shards of glass were found on the edge of the street and in the grass.

The explosion also blew out the window in the kitchen and living room of a neighboring apartment in the same building.

On Facebook, Austin appears holding a bong-type device in his profile photo and made several references to his marijuana business in public posts, including one from several hours before the explosion Sunday.
