Madison Whiddon, 17, killed, 4 teens injured and driver Anthony Box, 18, arrested after single-vehicle high-speed car crash on Highway 2 in Monroe, Washington

Emergency personnel responded to the scene, about three miles east of Monroe near the intersection of Highway 2 and Sofie Road, at about 11:40 p.m. Thursday after receiving reports of a serious crash. They found that five young people had been riding in the car, and three were ejected in the crash. The 17-year-old girl was pronounced dead at the scene, and the four others were injured. They were taken to the hospital, but their conditions were not immediately available.

The girl who died was from Sultan. Troopers say her younger sister was in the car, too. The 18-year-old was arrested on investigation of vehicular homicide and vehicular assault. Investigators say they are "confident" drugs were a factor in the crash. Prosecutors will ultimately determine charges.

The judge set Box's bail at $100,000, which is an amount Box's lawyer said his client can't afford to pay. Investigators found at least 3 cans of Dust Off, which is a known inhalent, in the car, records stated. Yeah, he crashed his car, but he's not guilty person of killing anybody," said Anthony Box's brother, Travis. Court records state Anthony Box admitted to deputies after the crash that he was the driver. Travis Box said his brother and several friends were on their way back from a trip to a nearby Walmart store when the crash happened.
