PLAINFIELD, Conn. (AP) — A U.S. Air Force member has been accused in Connecticut of sexually assaulting a 14-year-old girl he met online.

Exeter, Rhode Island, resident Nicholas Murphy is charged with sexual assault and illegal sexual contact.

Plainfield, Connecticut, police say the 26-year-old Murphy met the girl through social media. The girl was reported missing on Sept. 17, 2015. Police say she was with Murphy during that time.

Murphy has turned himself over to authorities. He’s being held on $50,000 cash bail and can’t be reached for comment. He’s scheduled to face a judge on Monday.

It’s unclear whether he has an attorney who could comment on the charges against him.

SAN DIEGO (AP) — Federal officials in San Diego say they have discovered an 800-yard-long secret tunnel under the U.S.-Mexico border, resulting in the seizure of more than a ton of cocaine and seven tons of marijuana.

The U.S. attorney’s office said Wednesday that the tunnel extends from a house in Tijuana, Mexico, to a fenced lot in a San Diego industrial area.

The tunnel was equipped with a rail system, ventilation, lights and a large elevator.

The tunnel exit on the U.S. side is about 3 feet wide and was covered by a trash bin. About 500 yards of the tunnel are on the U.S. side of the border.

Officials say six people were arrested in San Diego on Friday and charged with crimes involving drugs and construction of the tunnel.

KATY, Texas (AP) — Investigators say a man shot and killed his wife, son and daughter before killing himself in a Houston-area home.

The Fort Bend County Sheriff’s Office says the bodies were discovered Tuesday morning in the Katy area.

Sheriff’s spokesman Bob Haenel (HAN’-el) says it appears the man shot his family, including two children under the age of 5.

Haenel says a relative of the victims had asked deputies to check on the family, and that’s how their bodies were found.

Officials are trying to determine what prompted Tuesday’s shootings. Names of the victims and further details weren’t immediately released.

PHILADELPHIA (AP) — An eighth-grade girl has been charged with stabbing another eighth-grade girl with scissors at their Philadelphia elementary school.

A police spokesman said the 13-year-old girl was charged as a juvenile Wednesday with aggravated assault and related offenses.

District spokesman Fernando Gallard says the 14-year-old victim has been released from the hospital.

Gallard says the girls were fighting Wednesday morning in a hallway at the start of the school day when the 13-year-old grabbed the scissors and stabbed the 14-year-old in the upper chest and arm.

He says the victim is expected to return to school Monday and officials are meeting with her and her parents to develop a safety plan.

Gallard has said the two students “have a history.”

EAST PITTSBURGH, Pa. (AP) — Police say a Pennsylvania woman tortured her 2-year-old son with at least 15 cigarette burns while her boyfriend watched and laughed.

Police have jailed 19-year-old Anna Russell and 25-year-old Enrique (en-REE’-kay) Soto on charges including aggravated assault and conspiracy.

Police say the burns were inflicted on Aug. 1 and were discovered a week later when the boy’s grandmother took him to a hospital. Doctors told police the burns were “administered deliberately, in a chronological order, over a very short period of time in one sitting.”

Police have since interviewed the boy’s 3-year-old sister who told them Russell burned the boy while Soto watched and laughed.

Online court records don’t list an attorney for the East Pittsburgh couple, who face a preliminary hearing April 19.

SALT LAKE CITY (AP) — Authorities allege four men sexually assaulted a 9-year-old girl at a Utah home while her mother was in the garage smoking meth.

Sheriff’s officials say in court documents the assault occurred March 27 at a home in rural Uintah County, which borders Colorado.

Deputies say four men who were staying in the home raped the child, who later reported it to her mother.

The Uintah County Sheriff’s Office says the men have been arrested. It identified them as 36-year-old Larson RonDeau, 20-year-old Josiah RonDeau, 29-year-old Jerry Flatlip and 26-year-old Randall Flatlip.

Charges have been filed against Larson RonDeau. County Attorney G. Mark Thomas says he expects charges to be filed against the other three in the next few days.

None of the men has a listed phone number or appears to have an attorney to comment on his behalf.

CHICAGO (AP) — The first major research of its kind shows that cholesterol-lowering statins can prevent heart attacks and strokes in a globally diverse group of older people who don’t have heart disease.

The results from 21 countries bolster recommendations on who should consider taking the drugs.

The aim was to prevent heart disease using a statin alone, blood pressure drugs or a combination of the two. The patients in the study did not have heart disease and faced lower risks of developing it, and the statin approach worked best.

The research was published online Saturday in the New England Journal of Medicine and presented at an American College of Cardiology meeting in Chicago.

WILLIAMSTOWN, Pa. (AP) — Authorities say a 15-year-old Pennsylvania boy fatally shot his 18-year-old brother because both were interested in the same girl.

Dakota Thornton has been jailed and charged as an adult with criminal homicide and possessing an instrument of crime.

Dauphin County District Attorney Ed Marsico says Thornton shot his brother, Dominick, shortly before 2 a.m. Wednesday.

State police say Thornton told them he loaded a .410-gauge shotgun a couple minutes before the shooting.

A criminal complaint says Thornton told police he “shot and killed his brother over the fact that he was romantically interested in his brother’s girlfriend.”

The shooting occurred at their home in Williamstown, about 30 miles northeast of Harrisburg.

Online court records don’t list an attorney who could comment for Thornton. He has a preliminary hearing April 27.

DALLAS (AP) — Three children are dead and two drivers and a teenage passenger are hospitalized after one car slammed broadside into another carrying the children at a western Dallas intersection.

A Dallas police statement says a car driven by a man was westbound on Singleton Boulevard about 5:30 p.m. Monday when a car with a female driver and four children as passengers pulled out from a side street. The man’s car slammed into the left side of the second car.

Police Senior Cpl. Melinda Gutierrez says three children, all younger than 13, died shortly thereafter at Children’s Medical Center of Dallas, and a 13-year-old was taken to an unspecified hospital in unknown condition. She says both drivers received non-life-threatening injuries.

Investigators suspect excessive speed factored in the crash. Identities are being withheld.
