Jury selection began today in the murder trial of David Barajas, who is accused of killing a drunk driver who fatally struck Barajas' two children in Alvin in 2012.

Barajas has denied shooting Jose Banda, who allegedly ran into Barajas' 11- and 12-year-old sons "as they pushed the family's broken-down truck down a dark, narrow road just 50 miles from their home," according to Fox News.

Legal experts say prosecutors have a tough case -- "no weapon was recovered, no witnesses identified him as the shooter, and many in Barajas' community have strongly sympathized with him," according to the Fox report.

A "Free David Barajas" Facebook page has 4,219 likes.

But Banda's common-law wife, Felicia Leija, told Fox that "What [Barajas] did wasn't right. For other people to say they would have done the same thing...you don't know what you would have done." (Banda leaves behind a 2-year-old daughter who was born just months before he was killed).

Barajas' attorney said Barajas didn't own a gun, but "a search of Barajas' home found ammunition consistent with the bullet that killed Banda," according to Fox.

We'll keep you posted. This is truly a tragic story.
