Texas teenager sentenced to 40 years in prison after killing one student and wounding another in a school shooting

A 16-year-old who opened fire at a Dallas-area school earlier this year, killing one student and wounding another, was sentenced Thursday to 40 years in prison on murder and attempted murder charges, prosecutors said.

The teenager, who was 15 at the time of the shooting, had admitted being the shooter and asked a jury to decide his sentence, the Tarrant County District Attorney's Office said in a news release. Because he is a minor, the prosecutor's office withheld the teenager's name.

Before the first bell rang on March 20, the teenager fired a shotgun at a group of students waiting for the doors to unlock at Lamar High School in Arlington, prosecutors said. 16-year-old Ja'Shawn Poirier was killed and a 16-year-old girl was hit in the face by shrapnel.

The teen will be sent to the Texas Department of Juvenile Justice and before his 19th birthday the judge will decide whether he should go to the Texas Department of Criminal Justice to serve the remainder of his sentence.

Prosecutors had tried to try the teen as an adult, but the judge denied the request and kept him in juvenile detention.

The jury gave the teenager the maximum sentence. The teen's defense attorneys had asked for leniency, saying the teen had essentially raised himself.

Earlier this month, federal prosecutors said the teen's father was sentenced to more than six years in federal prison for being a felon and possessing a firearm. They said that after the school shooting, police searched the man's home and found papers for the shotgun and other firearms recovered in the shooting.
