As we head into the last weekend of summer, here is a roundup of gun news:

* In June we featured the story of Scott Hazelbaker, who accidentally shot and killed his 18-year-old daughter Emily, whom he called his best friend, in the kitchen of their Ankeny, Iowa, apartment. “She was just an angel here on earth,” he told local news station KCCI shortly after the shooting. “I miss her so much.” Police said Hazelbaker, 51, pointed a handgun at her thinking the safety was on. This week he plead guilty to involuntary manslaughter and faces five years in prison.

* An investigation by Mayors Against Illegal Guns found that background checks aren’t done in a majority of Internet firearm transactions, a loophole the Times brought to national attention in April. The office of New York City Mayor Michael Bloomberg found that 62% of online gun sellers disregard federal laws, selling firearms with no questions asked. “If one in 30 people on a Boeing 747 were on a terrorist watch list, the plane would have 22 suspected terrorists on it, something no passenger or airline would tolerate,” Bloomberg said.

* A study conducted by doctors at N.Y.U. and Columbia University and published by the American Journal of Medicine found that the more guns there are in a country, the more people die from guns—and the U.S. far and away leads the pack in both gun ownership and gun deaths. On the opposite end of the spectrum, Japan, which has the lowest rate of gun ownership, has the fewest gun deaths. The physicians examined data from 27 developed countries, using gun ownership figures from the Small Arms Survey and the World Health Organization.

* Police officers in Phoenix, Ariz., worked overtime to mark nearly 2,000 weapons from a gun-surrender program for destruction before a new state law required the firearms to instead be sold. The department clocked nearly 175 hours of overtime, plus time donated by reserves and personnel from other agencies, to process the guns before the law took effect Sept. 13. “I’m very happy we were able to get these destroyed before the law took effect,” Hildy Saizow, president of Arizonans for Gun Safety, said. “That’s what we promised the public.” Charles Heller, spokesman for the Arizona Citizens Defense League, said the additional $10,000 Phoenix spent to process the weapons could have been better used arming and training residents. The gun surrender netted a shotgun and four stolen weapons, one of which was linked to a shooting.
