Arlington Lamar High School mourns loss of student in deadly shooting.

Students returned to Arlington Lamar High School just two days after a shooting outside the school killed 16-year-old Ja'Shawn Poirier and injured another student. Additional security and law enforcement were present on campus, along with counselors and other personnel. The 15-year-old suspected shooter, also a student at the school, appeared in court and faces a capital murder charge. Several local school districts are showing support for Arlington Lamar and their students by wearing the school's colors.
