A father faces trial on charges that he fatally shot a drunken driver who killed his two sons in a wreck in rural Southeast Texas.

Opening statements are expected Tuesday in the murder trial of David Barajas in Angleton.

Authorities say Barajas fatally shot Jose Banda after the December 2012 accident near Alvin, about 30 miles southeast of Houston. Barajas' sons, 12-year-old David Jr. and 11-year-old Caleb were killed in the wreck.

Defense attorney Sam Cammack says his client did not kill Banda.

No witnesses have named Barajas as the shooter. Authorities never recovered a weapon.

If convicted, Barajas faces up to life in prison.
