(Scroll down for video) A drunken driver was shot and killed moments after he killed two children in a car crash, according to police reports.

Mourners packed a memorial service on Wednesday, for two young brothers, who were killed by a drunk driver while helping their father push a broken down family van through a narrow and dark road, just 50 yards from their Houston, Texas, home.

Meanwhile, Brazoria County sheriff investigator Dominick Sanders said that detectives had no formal suspects in the shooting death at the scene on Friday night of Joseph Banda, the 20-year-old driver who crashed into the Barajas brothers, David and Caleb, and their father.

The death of Banda has been declared a homicide, but Sanders said investigators had not interviewed the father of the boys, who was injured, or their mother, Cindy Barajas, who was in the van with her eight-year-old daughter and 3-month-old son.

"We hope to be able to talk to them soon," Sanders said, adding that the sheriff's office is trying to locate anyone who may have been at the scene of the accident.

David Jr., 12, died at the scene and Caleb, 11, died in a hospital. Neighbors said they heard shots two minutes after the accident, which occurred about 50 yards from their home near Alvin, about 30 miles southeast of Houston.
