Reading police are searching for the person who, they say, intentionally set a home on fire.
Around 3 a.m. Tuesday, firefighters were called to the 1000 block of Buttonwood Street in Reading.
Investigators are convinced that the two-alarm fire that damaged three row homes is a case of arson.
In addition to the fire department's investigation, the Reading Police Department assigned a detective to the case to assist in the investigation, officials said.
Meanwhile, neighbors say they are still on edge.
"I noticed the flames from two doors down and I called the cops immediately," said Jenny Hernandez.
"People that do that is ridiculous," said neighbor, Virgilia Keller. For Keller this fire opens old wounds. She says in 2010, her previous home near Mt. Penn was set on fire.
"I lost my three pets," Keller said. "I really feel for the family."
Helping Reading authorities get to the bottom of this crime, was the Allentown Fire Marshal, using a specially trained K9 dog.
The displaced families are being assisted by the American Red Cross.
Samples collected from the damaged homes are being analyzed for clues, authorities said.
