Israel Melendez was cleaning his truck outside his home on St. Paul's West Side about 2 p.m. Saturday when he heard the explosion.
He looked up and saw flames and debris falling around a house on the corner of Hall Avenue and W. Baker Street.
He knew the person who lived inside, Michael L. Schultz. Schultz, 74, lived by himself. He had had heart surgery and a stroke, neighbors said.
Melendez, 48, ran to the large stucco house accompanied by another neighbor, Paul Warner, 53.
They tried to get the door open, but couldn't. So Melendez broke through the window on the first floor. He stepped inside and saw Schultz lying on the living room floor.
He grabbed Schultz's shirt and pulled. With Warner's help, he got Schultz out through the window.
"There were flames everywhere, bro," Melendez said.
Warner told friends and relatives that he could feel the heat of the fire on the back of his neck as he pulled the victim away from the house.
