A meth lab found in an abandoned Texas Burger King is being investigated. Officers in San Marcos say they received a call over the weekend about something fishy going on at the place and found a backpack filled with meth making material at a homeless camp behind the restaurant. Multiple units arrived to clean the place up but one officer did need medical treatment after coming into contact with an acid used in the lab. The portable lab was dismantled and it took most of the day before the location was given the all-clear.
