LEWISVILLE (February 2, 2012)—John Casias, the son of a missionary couple killed in Mexico, said Thursday there will be a funeral service at the couple’s home church in the Dallas area.

Casias says he is working to repatriate the bodies of his parents John and Wanda Casias from northern Mexico, where they were killed Tuesday in what evidently was a home invasion.

The couple spent 29 years doing missionary work in Santiago, about 20 minutes from Monterrey in Nuevo Leon state.

A service was held Thursday at their church in Mexico, but Casias said he hoped to have the bodies flown to the U.S. later in the day.

The date of the service at Liberty Baptist Church in Lewisville will be determined once the bodies have returned to the U.S.

Valerie Alirez, the eldest child of the slain pastor, told The Associated Press from her home in Greeley, Colo., that one of her brothers found her father and stepmother Tuesday dead in their home in Santiago, Nuevo Leon.

The family was originally from Amarillo, but Alirez said her father and stepmother moved to Mexico in 1979 and made it their home.
