UVALDE, Texas (KTRK) –

A couple who had just been married for an hour and a half was killed over the weekend when their helicopter broke down in Uvalde, Texas.

The groom's grandfather, William Byler, confirmed to Eyewitness News that the plane crashed on Saturday on the family ranch. His grandson, Will Byler, his new wife, Bailee Ackerman, and the pilot of the plane are all dead.

The confirmation comes after the National Transportation Safety Board tweeted Sunday about an accident involving a Bell 206B helicopter, a two-bladed model, with one or two reactors. The incident occurred about 15 miles northwest of Uvalde, according to NTSB information.

Officials are investigating and the San Antonio Fire Department has deployed 10 units to help. The investigative body did not immediately confirm the number of people killed.

The couple's wedding portal on the planning website The Knot also confirmed that their wedding would be held Nov. 3 in Uvalde on the family ranch Byler. The engagement photos also show Byler in his cowboy hat in various forms of embracing with Ackerman.
