Lattin's attorney disagrees, arguing there is no credible way to determine when a person has smoked marijuana. He also says the drug may have gotten into his client's bloodstream through secondhand exposure.

Lattin supervises a team that investigates fatal crashes. He voluntarily submitted to the blood test that led to the charges against him.

The offense carries up to 20 years in prison.

MONDAY

TERM LIMITS ARGUED

A legislative lawyer who said voters didn't understand what they were doing when they approved term limits 12 years ago was peppered with questions as Nevada Supreme Court justices reviewed whether the limits are constitutional.

Kevin Powers of the Legislative Counsel Bureau was the only attorney at Monday's hearing in Carson City arguing that term limits are not allowed under the state constitution.

The high court's decision on the issue is pending.

TUESDAY

FINAL TABLE SET

Nine players advanced to the final table of the World Series of Poker, but they will have to wait four months for a shot at the $9.12 million jackpot.

The unprecedented delay is meant to increase promotional opportunities for the tournament and make the final table easier to televise.

The nine finalists emerged from a field of 6,844 players. When play resumes at the Rio in November, Dennis Phillips of St. Louis will be the man to beat with a chip lead of almost $2 million.

WEDNESDAY

SCHOOL BOND DELAYED

Citing slow growth and a sour economy, Clark County School Board members announced plans to pull a $7 billion bond question from the November ballot.

The initiative could have paid for 73 new schools over the next decade, but board members say they don't want to ask the public for more money when the need is not immediate.

The board plans to bring the measure back in 2010.

THURSDAY

LAKE GOES UNDER

Lake Las Vegas filed for Chapter 11 in what could turn out to be one of the largest bankruptcies in Nevada history.

"Extremely challenging real estate market conditions" is one reason cited for problems at the 3,592-acre residential and resort development built around an artificial lake in Henderson.

One of the companies involved reports debts of as much as $1 billion and assets of as little as $100 million.

FRIDAY

LOST ANGEL FOUND

Six years after a biker melee in Laughlin ended in three deaths -- and long after gang members were tried, convicted and jailed for the violence -- a missing Hells Angel accused of firing his gun that day has turned himself in.

It's not clear where Frederick Donohue, 43, has been since the 2002 biker battle, and he's not talking.

Prosecutors say Donohue was one of three shooters at the riot, but not a key shooter. He faces the same 32-count indictment the others faced.
