LAS VEGAS (AP) -- Former state Sen. John Lee has ousted incumbent Shari Buck in the North Las Vegas mayor's race.

The ouster comes after Lee out-fundraised his opponent by nearly $55,000 and earned more than half of the votes in the Tuesday election.

The Las Vegas Review-Journal reports Buck, who's the city's first elected female mayor, was opposed by public employee unions. Lee, who's a three-term Democratic state lawmaker, had the endorsement of the North Las Vegas Police Supervisors Union and the Las Vegas Metro Chamber of Commerce.

In nearby Henderson, Mayor Andy Hafen staved off six challengers to win another four-year term.

Hafen has been mayor since 2009, and had joined the City Council in 1987.

A little more than 12 percent of active registered voters participated in the Henderson election.

LAS VEGAS - The primary election for the valley's municipal races takes place Tuesday, but election officials expect very low turnout.

During last year's presidential race, 80 percent of registered voters voted. Election officials expect 10 percent turnout for the municipal primary, in part because many voters will only see one race on their ballots.

Less than 7,000 people voted early in Las Vegas.

Candidates in Henderson, North Las Vegas, Mesquite and Las Vegas are running for city council, mayor and municipal judge. The ballots are small, but the primary election is important. If a candidate wins by a 50-percent majority, that candidate bypasses the general election and wins the seat. The candidate could be sworn into office as early as this month.

Austin Sonetti has little brain function and suffers seizures. He is only 9 years old.

Austin is this way because he fell into a backyard pool when he was just 17-months-old. His brain was deprived of oxygen for 39 minutes. He survived but barely.

"He is now left in a vegetative state. He suffers seizures. He has a trach (tracheotomy tube). He has recurrent pneumonias," Austin's mother Cierra Sonetti said.

Austin is an example of just how dangerous a body of water can be. Three adults were in the backyard with him when he silently slipped into the pool in April 2005.

It is a case like the Sonetti family that the Southern Nevada Child Drowning Coalition is hoping to prevent this summer.

The group held an April Pool's Day event Monday at a pool in North Las Vegas to get the word out about the dangers of pools.
