When she couldn't find him, she knew right away where he was: He had run into the burning house to try to help the people inside.
"I knew he'd do that," Romero said. "I knew where he was."
Early Tuesday, Michael Romero, a certified EMT, kicked in the door of his neighbor's house and helped three adult women, who were asleep, get out safely.
"If my house were on fire, I'd want someone to return that favor," said Michael Romero, who has worked for Wendover Ambulance.
Investigators say the fire near 8600 West and 3400 South was intentionally set by the estranged husband of one of the female residents. Travis Dominguez, 25, was booked into the Salt Lake County Jail for investigation of aggravated arson and burglary.
"It didn't surprise us at all," said Cassie Dominguez when she heard about who was arrested.
She has been going through a volatile divorce with her estranged husband for several months. Several times Travis Dominguez threatened her, she said.
