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 (buh-RAH'-hus) 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.
