Authorities worked over the weekend to tighten security measures around the McLennan County Courthouse for the first trial of a May 2015 Twin Peaks shootout defendant.
A temporary, metal fence was placed around the perimeter of the 115-year-old building and officials have blocked access to curbside parking spots on three sides of the courthouse.
Black curtains have been placed over windows in areas where the jury or those involved in the trial could be viewed walking from the outside of the courthouse and a canvas tent was erected in the alley between the courthouse and the annex to shield the jury as they walk between the buildings.
After filling out questionnaires Monday, prospective jurors were told to report at 9 a.m. Tuesday for the beginning of jury selection in the trial of Jacob Carrizal, 36. Court officials expect the trial to last about two weeks.
