A house in the 3300 block of Denison exploded Tuesday morning. Flames spread to two neighboring homes.
When crews arrived at the address, the home was already destroyed.
There were nine people in the three affected homes, including one child.
Firefighters rescued two people from the basement of the home. A 54-year-old woman, suffering from smoke inhalation, was rushed to MetroHealth Medical Center.
"We didn't get water on the fire right away. The first 10 companies were just trying to get people out of that explosion," said Mike Darnell, assistant chief of Cleveland Fire.
Authorities say the explosion is suspicious. Michael, who lives across the street, said he heard the explosion and then saw two men fleeing.
"I grabbed my phone and ran down the stairs and screamed out in the neighborhood, 'Fire! Fire! Fire!' So everybody could hear me. I started chasing the suspects," he said.
He couldn't catch them, but says the suspects dropped two bags, including a zipped duffel bag.
"The other one was a garbage bag and it had a gas can in it. You could smell the gas from it," said Michael.
Firefighters found two gas cans around the corner from the scene. They say it was a huge explosion because the cans were lit simultaneously.
