WASHINGTON (AP) — President Barack Obama is mourning what he called “yet another mass shooting” in the United States that he says took the life of American patriots.

Obama promised to make sure, quote, “whoever carried out this cowardly act is held responsible.”

He said several people were shot Monday morning at the Washington Navy Yard about 3 1/2 miles from the White House, and some were killed.

He said the victims were “courageous Americans” who knew about the risks of serving overseas, but wouldn’t have expected such “unimaginable violence” at home.

The White House says the president has been receiving frequent briefings about the unfolding situation by senior aides.

WASHINGTON (AP) — Police say at least 12 people have died in the shootings Monday at the Washington Navy Yard. One gunman is dead. Police now say a man who was seen in a military-style outfit and had been sought in connection with the shooting rampage has been identified and is not a suspect. The police chief says there is no indication of a possible motive at this time.

A Washington DC police officer is among the injured, and was reported in surgery.

Earlier in the day, the U.S. Navy said it was searching for an active shooter at the Naval Sea Systems Command headquarters, where about 3,000 people work.

The Federal Aviation Administration lifted a hold on departing flights from Ronald Reagan Washington National Airport.

A gunman was armed with at least three weapons, including an assault rifle, according to local television station WJLA, which cited unidentified Washington police officials. At least four people, including a Washington police officer, were shot, the station said.

The shootings happened at about 8:20 a.m. at the headquarters of the Naval Sea Systems Command on Isaac Hull Avenue on the grounds of the historic Navy Yard.

JEFFERSON CITY, Mo. (AP) — The Missouri State Highway Patrol says 72 people have successfully petitioned to be removed from the state’s sex offender registry under the provisions of a 2009 law.

The law lets people who were 19 or younger at the time of their offenses ask to be taken off the registry if their victims were at least 13 years old and the sexual offense did not involve force. Decisions on whether to remove people from the list are made by judges.

On Wednesday, lawmakers will consider whether to override Gov. Jay Nixon’s veto of a bill that would remove hundreds of additional people from the state’s online sex offender list. That bill would automatically remove juvenile offenders from the website and allow them to eventually seek removal from law enforcement lists.

COLUMBIA, Mo. (AP) — Soaring temperatures are getting the blame for an unusual number of medical emergencies at the Missouri-Toledo game.

University of Missouri police Captain Scott Richardson says at least 110 medical emergencies were reported Saturday, and most of them were heat related.

None of the injuries was serious.

Temperatures had risen to nearly 96 degrees on campus during the mid-afternoon game at Faurot Field. Nearly 57,000 people turned out to watch Missouri beat Toledo 38-23.

MANHATTAN, Kan. (AP) — A panel of six former agriculture secretaries will give the next installment of the Landon Lecture series at Kansas State University.

 

The October 21st event at McCain Auditorium will take the form of a question-and-answer session. The panelists will be Mike Johanns, Ann Veneman, Dan Glickman, Mike Espy, Clayton Yeutter and John Block.

University chief of staff Jackie Hartman says that having six agriculture leaders share the same stage is “nothing short of monumental.” The speakers were picked as the school celebrates its 150th anniversary and birth as a land-grant institution.

The Landon Lecture is named for Governor Alf Landon, a Republican who was Kansas governor from 1933 to 1937. Landon lost to Franklin D. Roosevelt in the 1936 presidential election.

PINE BLUFF, Ark. (AP) — Police in the southeast Arkansas city of Pine Bluff say a 107-year-old man is dead after SWAT officers shot back at him during a standoff at a home.

Pine Bluff Lt. David Price tells KATV that police officers called to the home Saturday were told Monroe Isadore had pointed a weapon at two people there.

Officers had the threatened pair leave the home and approached a bedroom. Police say Isadore shot through the door at officers but missed hitting them.

More officers were called, including a SWAT team. They confirmed Isadore had a handgun.

Police say SWAT officers released gas into the room when negotiations didn’t work. They say Isadore shot at officers and they fired back, killing him.

HOLLISTER, Mo. (AP) — Officials at a southwest Missouri nonprofit say a large cash gift may have been made by mistake, and they hope to find the possibly unwitting donor.

Selfless Blessings Incorporated serves people in need in Taney County. The organization says a volunteer came across the cash while sorting donated items at its storefront location in Hollister.

The amount of money hasn’t been revealed.

It was enough to raise concern. Selfless Blessings’ founder, Andrea Berdine, said in a news release Friday the organization wants to be sure the cash wasn’t someone’s personal savings that got donated by mistake.

The group says anyone wanting to claim the cash has 59 days to do so and must be able to provide certain identifying details.

EL DORADO, Kan. (AP) — A man captured after a four-day search across southern Kansas has been charged with attempted capital murder in the shooting of a Butler County sheriff’s deputy.

Forty-one-year-old Jan Kilbourne made a first appearance Friday afternoon in Butler County District Court. Kilbourne’s court-appointed lawyer did not object when the state requested he be held on $1 million bond.

Kilbourne had been sought since early Monday, when the deputy was shot in the shoulder during a traffic stop near Augusta. The deputy is recovering at home.

Wichita police found Kilbourne around 3 a.m. Friday in a car outside a home. He was arrested without resistance.

The Butler County prosecutor cited Kilbourne’s previous criminal convictions in asking for the high bond.

Kilbourne declined to speak in court.

ST. LOUIS (AP) — A rural Missouri man charged with infecting another man with HIV is now facing charges that accuse him of risking infection to three other partners.

Stoddard County prosecutor Russell Oliver says David Mangum 36, of Dexter, Missouri is now facing 21 additional counts for having unprotected sex with three men without telling them he was HIV-positive.

Mangum is jailed without bond.

His attorney did not respond to interview requests.

Mangum was arrested last month after a man with whom he’d been intimate tested positive and alerted police. The new counts are a lesser charge because the new accusers are not HIV-positive.

Mangum claims he had sexual contact with as many as 300 people since being diagnosed a decade ago. He moved to Missouri two years ago from Dallas, Texas.
