Authorities have charged two suspects in a deadly shooting at a house party in suburban Houston that left two teenagers dead and 20 hurt.

The Harris County Sheriff's Office announced that 21-year-old Willie Young and 18-year-old Randy Stewart were arrested Monday morning.

Young is charged with deadly conduct while Stewart is charged with aggravated assault.

Harris County Sheriff Adrian Garcia says Saturday's shooting in Cypress, an unincorporated area about 25 miles northwest of Houston, began when someone fired a pistol in the air in celebration. In the ensuing confusion, someone else began firing into the crowd, causing people to stream into the narrow street.

Seventeen-year-old Queric Richardson died at the scene and a 16-year-old girl, whose name has not been released, died at a hospital.
