MARIJUANA-DUI

Arizona court rules on DUI law for marijuana users

PHOENIX (AP) - The Arizona Supreme Court has ruled that the presence of non-impairing marijuana compounds detected in a person's body does not give authorities the right to prosecute under Arizona's driving under the influence laws.

Last year, the state Court of Appeals upheld the right of authorities to prosecute pot users for DUI even when there is no evidence of impairment.

The Supreme Court opinion released Tuesday notes that while Arizona statute makes it illegal for a driver to be impaired by marijuana use, the presence of a non-psychoactive compound does not constitute impairment under the law.

The opinion focuses on two chemical compounds in marijuana that show up in blood and urine tests - one that causes impairment and one that stays in the system for weeks but doesn't cause impairment.

MEDICAID EXPANSION-ARIZONA

Court revives challenge to Arizona Medicaid plan

PHOENIX (AP) - The Arizona Court of Appeals has revived a lawsuit challenging Gov. Jan Brewer's expansion of the state's Medicaid insurance plan for the poor.

The court ruled Tuesday that lawmakers have the right to sue over a hospital assessment that funds the expansion. Republicans in the House and Senate sued last year over the assessment, arguing that it is essentially a tax that required a two-thirds majority vote to pass. Only a bare majority passed the expansion.

A Maricopa County judge in February dismissed the case, saying lawmakers did not have the right to sue. The judge said it is the legislature itself that decided if a supermajority vote is needed.

But the appeals court rejected that decision and sent the case back to Judge Katherine Cooper for more action.

TEMPE-COLD CASE ARREST

Tempe police: Phoenix Man arrested in 1999 killing

TEMPE, Ariz. (AP) - An arrest has been made in a 1999 cold case in the Phoenix area.

Tempe police say detectives and U.S. Marshals Service officers arrested 42-year-old Homer Moore of Phoenix on suspicion of first-degree murder in the suffocation killing of 19-year-old Karam Hussein Jabbar.

The victim's bound body was found in the trunk of a vehicle in a Mesa grocery store's parking lot. An autopsy determined that Jabbar's death was due to asphyxia partly due to a plastic bag placed over the head.

The body was found about week after Jabbar went missing.

Moore was arrested Monday in Glendale. Tempe police say they're seeking additional suspects in the case.

DEMOCRATIC CONVENTION

Democrats eye 15 cities for 2016 convention

WASHINGTON (AP) - The Democratic National Committee has asked Phoenix and 14 other cities to make a pitch to host the presidential nominating convention in 2016.

The DNC on Tuesday said the party will accept proposals through June 6 and will pick a host city either late this year or early in 2015.

In addition to Chicago and New York, the cities under consideration include: Atlanta; Cleveland; Columbus, Ohio; Detroit; Indianapolis; Las Vegas; Miami; Nashville; Orlando; Philadelphia; Phoenix; Pittsburgh and Salt Lake City.

Some cities seem more likely than others. For instance, President Barack Obama, who will be leaving the White House in 2017, calls Chicago home and his potential successor Hillary Rodham Clinton is from Illinois. Clinton also represented New York in the Senate.

PHOENIX FIRE

Phoenix fire sent up plume of black smoke

PHOENIX (AP) - Phoenix firefighters are mopping up a fire at an oil tanker business that critically injured two men and sent up a massive plume of black smoke over the city.

About 20 engines and ladder trucks were dispatched. Television footage showed firefighters shooting water and foam at the flames and the smoke plume gradually dissipated.

Two men are hospitalized, one with burns on 50 percent of his body and the other with 15 percent.

Nearby Sky Harbor International Airport temporarily shut down its north runway but spokeswoman Heather Lissner says it is back in operation. The temporary closure didn't cause flight delays because planes used two other runways.

However, the light rail system reports delays because some of its tracks are near the blaze.
