Nation: An American sailor has died of his injuries suffered in the Chattanooga mass shooting, bringing the number of dead to six, including the gunman. Randall Smith of Ohio was 24.

Investigators are looking into what the Chattanooga shooter did during a seven-month trip to Jordan last year, and whether there’s any connection to his decision to shoot up two military offices. Mohammad Youssuf Abdulazeez was armed with two long guns and a pistol when he killed four Marines at a Naval Reserve center.

More Marines died in the shooting than Afghanistan so far this year. One of them was Gunnery Sgt. Thomas Sullivan, 40, who had been wounded during two tours in Iraq and was getting close to retiring.

>Wildfire over ran the 15 Freeway east of Los Angeles yesterday, forcing drivers to abandon their cars in a traffic jam and watch them burn. No one was injured, but it was frightening. About 20 cars, a boat, and an eighteen-wheeler burned. The fire grew to 3,500 acres.

Permawar: An estimated 115 people were killed today in a suicide bombing at a crowded marketplace in Iraq’s eastern Diyala province. The mostly-Shiite victims were gathered to mark the end of the Islamic holy month of Ramadan. An Islamic State group has claimed responsibility.

In a separate development, Islamic State fighters have made their own crude chemical artillery shells and fired them at their Kurdish opponents in Iraq and Syria, according to investigators in the field. The shells appear to have been loaded with agricultural or industrial chemicals, not the chemicals designed for warfare. But the discovery is being taken as another escalation of the mad methods of ISIS.

Ice Planet: NASA scientists continue to be thrilled by the pictures of Pluto sent back to earth by the New Horizons spacecraft. They see 11,000-foot mountains as big as the Rockies adjacent to icy plains laced with gullies. The scientists describe Pluto as “geologically active,” meaning that its surface is still changing.

The Obit Page: Bill Arnsparger, the defensive coach whose “No Name Defense” helped the Miami Dolphins win the Super Bowl in 1973 and 1974, has died at age 88. The 1973 Miami team had the only perfect record in NFL history.

Arnsparger was a failure with a losing record as head coach with the New York Giants, but a genius at a defense that left opponents confused about who was who and doing what. One of his Miami players once said, “Nobody else runs stuff like we do, where the defensive end comes out in coverage, the linebackers play like linemen, the linemen play like linebackers, the stunts are different on every snap.”

College Bound: Anders Brevik, the Norwegian mass murderer who killed eight people with a bomb before gunning down 69 campers on an island in 2011, is serving 21 years in prison but he was just admitted to Oslo University to study political science. The University said Brevik met the admissions requirements. Makes you wonder what he wrote in his personal essay.

Sayonara: The designer of the giant Olympic stadium for the 2020 games in Tokyo sought the limits of Olympic excess and found them. The enormous white Japanese beetle of a sports stadium would cost $2 billion to build, making it the most expensive stadium in the world — if it were ever to be built. But Prime Minister Shinzo Abe has decided to scrap the design and start over with a blank piece of paper, not a blank check.
