The officers, both veterans, are in stable condition and are expected to make a full recovery, said Mr Stollsteimer.
Shortly after the officers were shot, the house was engulfed in flames. While it was not immediately clear what had started the fire, authorities fear people were inside the house.
Around six to eight people are unaccounted for according to Mr Stollsteimer.
He confirmed that authorities know there were “a lot of people living in that house, including children”.
“It is our terrible fear that they may be inside that house when it was burned,” he said. “We are hopeful that that is not true.”
Sharon Johnson, a crossing guard who witnessed the shooting, told NBC10: “I was there, a cop came flying around the corner. He got out and then he’s in front of the house talking to two people. And then all of a sudden I heard six or seven gunshots. Cops got down on the ground and I ran and took off.”
The fire was still burning late on Wednesday evening and the house was deemed too dangerous for authorities to enter the property.
“There’s going to be a lot of work ahead of us,” Mr Stollsteimer said. “Gruesome work.”
He predicted that the earliest authorities may be able to get into the property to confirm the number of people who died would be Thursday morning, if the fire had burnt out by then.
Authorities have not yet identified the family or possible victims.
