An illegal immigrant surrendered after fleeing the scene of a street racing crash that left a Texas pastor and his wife dead.

The sheriff's office said that 21-year-old Alexis De Larosa Sosa was racing his pickup truck against another car along a Houston freeway on April 12.

De Larosa Sosa blew through a red light at full speed, slamming into the car of Jesse Estrada and Maria Sabillon, then fled the scene on foot. The couple were pronounced dead on the scene.

Three days later, De Larosa Sosa turned himself in to the Harris County Sheriff's Office.

While booking him, authorities discovered he is a Mexican national who entered the U.S. illegally.

The victims' daughter-in-law said the family is grieving their loss but "feel blessed" to know the suspect is in custody.

"Our prayers have been answered," Denise Sabillon said. "We just want justice."

De Larosa Sosa is expected to be charged on two counts of homicide and fleeing the scene of a fatal accident.

A donation page for the funeral costs says Jesse Estrada and Maria were well-respected in their community and loved by many. They leave behind three sons and five grandchildren.

"Jesse Sabillon was a Pastor at Iglesia Neuvo Amanecer Batipst Church in Cloverleaf area.  He also was a well known carpenter who owned his business called JJ and Son Remodeling with his sons. Maria Sabillon was a retired home care giver for children with special needs."
