The mayor of Frisco has one sure vote if he chooses to run for re-election.
Mayor Maher Maso was driving home from a charity event when he spotted smoke.
"As I'm driving up Custer Road, I saw a little smoke, which quickly turned into a lot of smoke and caught my attention," he said.
As he got closer to the home along Custer Trail, he saw flames shooting from the back of the house.
Maso called 911 and walked up to the home, where he saw an older couple and their granddaughter watching television.
"When I saw through the glass of the front door, there was people in there," he said. "I knocked pretty hard -- probably scared the living daylights out of the couple."
Maso convinced the couple to get out of the house, even though they didn't recognize the Frisco mayor.
And Maso -- still in his coat and tie -- didn't wait for firefighters.
"I wanted to see if they had a hose, and there was a hose there," he said. "I just connected it up and poured some water on the fire. It was really that simple."
The fire was out by the time firefighters arrived, and damage was contained to the outside of the house.
Maso is reluctant to say he saved three lives, but he's pretty confident he earned at least two votes in the next election.
"After, we were talking, and then he says, 'You know, I'm glad I voted for you.' He goes, 'Next time, I'll vote twice for you,'" Maso said with a laugh.
According to a report in the Dallas Morning News, pool equipment had caught fire near Bob Pollock's garage. Later, investigators said squirrels may have chewed through insulation, exposing wires, the paper reported.
