UVALDE (AP) — A newlywed couple died when the helicopter they were flying in hours after their wedding crashed into a hill in the rugged terrain of Southwest Texas.

William Troy Byler and Bailee Raye Ackerman Byler, both 24, were killed in the crash shortly after midnight Sunday about 10 miles northwest of Uvalde and about 80 miles west of San Antonio, said Steven Kennedy, justice of the peace for Uvalde County Precinct 1. The 76-year-old pilot, Gerald Douglas Lawrence, also was killed, according to Kennedy on Monday.

The newlyweds were seniors at Sam Houston State University in Huntsville, according to The Houstonian, the university’s student newspaper. They married Saturday night at a large Byler family ranch near Uvalde and left aboard a Byler family helicopter after the reception, Kennedy said.

The crash happened about 15 miles from where the helicopter took off. The flight was to carry the newlyweds to San Antonio International Airport, where they were to board a plane for their honeymoon destination. It’s not clear where they planned to go for their honeymoon.

“It’s very rocky, rough terrain and this particular hill has a 400- or 500-foot rise,” Kennedy said.
