AUSTIN, Texas (AP) A new and worrisome school year begins Tuesday in Uvalde.

There is new high fencing around the Texas communitys public school campuses that still isnt finished, a heavy police patrol that many families dont trust and no classes ever again at Robb Elementary School, three months after a gunman with an AR-15-style rifle killed 19 children and two teachers inside two adjoining fourth-grade classrooms.

Ashley Morales is putting her son, Jeremiah, back in class because she says she has no other choice as a working single mother. She will drop him off outside Uvalde Elementary on the first day. She says parents wont be allowed inside.

Im just nervous, scared, said Morales, whose son was a third-grader last year at Robb Elementary and lost three friends in the May 24 massacre. During a recent Meet the Teacher night, she felt a rush of anxiety walking down the school hall.

Oh my gosh, its actually going to happen, she said. School is going to start.

Although school already started weeks ago in many parts of Texas, officials pushed back the first day of class in Uvalde after a summer of unfathomable heartache, anger and revelations of widespread failures by law enforcement who allowed an 18-year-old gunman to fire inside the adjoining classrooms for more than 70 minutes.
