Hazmat crews returned Friday to the Pine Township home where authorities said they found potentially dangerous chemicals and illegal drugs last weekend.

Authorities initially went to the house on Condor Lane in the Treesdale housing development in response to reports of a possible underage drinking party on April 27.

A State Police warning sign on the front of the home says "a clandestine laboratory for the manufacture of illegal drugs and/or hazardous chemicals was seized." It tells visitors to use caution in the area.

Officials said the hazmat crews were trying to sanitize the house on Friday so it can eventually be returned to livable.

“Everything is safe. Everything has been sanitized. The residents can now go about their daily routine,” Northern Regional Police Chief Bob Amann said.

Police walked door-to-door on Friday alerting neighbors that the situation taken care of.

Authorities said the alleged evidence confiscated from the house included suspected bomb-making materials and illegal mushrooms.

Police said one person was taken from the house to a local hospital the night of the bust. The identity and condition of the person was not released.

County tax records show the house is owned by Theresa Guagler, but neighbors said they believe she’s out of the state and possibly out of the country. The children’s father will be staying at the house with the 14- and 8-year-old kids.

Neighbors who live on Condor Lane said they were in disbelief after they were forced to evacuate their homes early Saturday morning.

“It’s disappointing because I see kids there and you never want them to get hurt,” neighbor Joe Romano said.

“I’m shocked that anything like this would happen in our neighborhood,” Evie Varshine said. “I never even hear of any thefts or anything in our neighborhood so we’re all surprised.”

Police have not said what charges will result from the situation.

“We are still looking into this and still testing the chemicals,” Amann said. “Until the results come back, no charges will be filed.”
