“We didn’t see the explosion but we felt it and my mom, she ran outside to make sure everyone was okay because she’s a nurse,” said Zion Dugger, a neighbor. “After a while we started to see flames coming out of the windows. It was really scary and there was a huge amount of smoke, too.”

Police said Thursday they found a hash oil extraction lab at the residence.

A family member also told CBS4 the two human victims’ conditions are improving.

Another neighbor, Jackie Porter, told CBS4 she feared the worst when she saw the firefighters treating the dog at the scene.

“All of a sudden I saw four paramedics on the ground, hunched over something. And I didn’t know at first. I was like ‘Oh no, they found the dog.’ And I thought the worst. And then I saw an IV bag pop up and they were giving the dog oxygen and fluids and they revived him and he’s okay,” Porter said.
