An Iowa teenager was found guilty on Thursday of second-degree murder and manslaughter in the shooting deaths of two students in January at an educational program for at-risk youths.
The teenager, Preston Walls, 19, of Des Moines, fatally shot a 16-year-old and an 18-year-old who were part of the Starts Right Here program on Jan. 23, the authorities said. The police said at the time that Mr. Walls was a gang member and that the victims were members of an opposing gang.
Mr. Walls had been charged with first-degree murder for both killings, but jurors appeared to partially agree with Mr. Walls’s claim during trial that he had shot both teenagers because he feared for his life.
During the episode, Mr. Walls also shot William Holmes, 49, who founded Starts Right Here. In that shooting, the jury found Mr. Walls guilty of assault causing serious injury.
If Mr. Walls had been found guilty of first-degree murder, he would have faced a mandatory sentence of life in prison. He instead faces a maximum sentence of 50 years in prison with the possibility of parole.
Mr. Walls’s lawyer, Darren Page, did not immediately respond to calls seeking comment on Thursday. The Polk County Attorney’s Office, which prosecuted the case, also did not immediately respond to a call and email seeking comment on Thursday.
When the judge read the verdict on Thursday, Mr. Walls stood, looked toward the crowd in the gallery and cried.
On the afternoon of Jan. 23, Mr. Walls walked into a common area at Starts Right Here, carrying a handgun with an extended ammunition magazine, the authorities said. Mr. Holmes tried to escort Mr. Walls out of the area before he began shooting, according to the authorities.
After shooting at the two teenagers and Mr. Holmes, Mr. Walls fled on foot, the police said.
Mr. Walls had said during his testimony in court that he had felt threatened by the two teenagers and “felt like they were going to kill me.”
“I was going to be in a situation where I could possibly die,” Mr. Walls said. “And I was scared. I acted out of fear. It was a reaction.”
Prosecutors, however, argued that the shooting was premeditated and that Mr. Walls’s self-defense claim was “ridiculous,” The Des Moines Register reported.
Bravon Tukes, who is accused of picking up Mr. Walls after the shooting and driving him away, will stand trial on murder charges on Oct. 2, The Associated Press reported.
