PRINCE GEORGE’S COUNTY, Md. (DC News Now) — Police said Friday that they arrested 17-year-old boy from Glenarden for shooting and killing a 16-year-old high school student in Lanham.

“We do unfortunately have the the loss of a life of a sister, a daughter, a sibling, an individual that had befriended several individuals in this community and that is a tragic, tragic situation,” said Prince George’s County Public Schools Superintendent Millard House III during a press conference on Friday.

Jayda Medrano-Moore of Greenbelt died Monday, Sept. 11.

“It was a shock to myself and the police department. She was a bright student, a great athlete, with even a brighter future,” Prince George’s County Police Chief Malik Aziz, said. “Now we know it was another juvenile arm with a gun who stole her future and shattered her family.”

The Prince George’s County Police Department (PGPD) said there was a fight involving two groups of people in the 9800 block of Palamar Dr., near DuVal High School. Medrano-Moore, who was a student there, was walking down Palamar Drive when the fight started and the shooting took place.

PGPD said Friday that the groups involved in the fight had an ongoing dispute. Detectives think Medrano-Moore tried to intervene when she was shot.

During the news conference, county leaders expressed their frustrations with violence involving youth.

“I’m frustrated that the violent few are disrupting the education and the promising future of our great children in Prince George’s County,” Aziz said.

State’s Attorney Aisha Braveboy said her office is taking every case seriously, and holding everyone accountable, no matter their age.

“These are serious crimes that carry life sentences. When you make decisions, we have to make decisions, and the decision of my office is to hold you fully accountable, responsible for your actions,” said Braveboy.

Leaders along with County Executive Angela Alsobrooks are pleading with the community to be more involved to help curb the violence in the community.

“People deserve to live in places that are safe and our kids deserve not to die right near their schools and in their homes and communities,” Alsobrooks said.

“This issue will not be resolved simply by the government. It will not be resolved by the police. It cannot just be resolved by the state’s attorney, it must be resolved in the homes and in the communities of these children from their parents to the aunties, uncles godparents,” she added.

Prior to the shooting, DuVal High School was scheduled to be part of the second phase of metal detector installments throughout Prince George’s County Public Schools high schools. Because of the shooting, the school received metal detectors on Wednesday, Sept. 13, two days after Medrano-Moore died.

Police said the boy faces charges of first degree murder, second degree murder, first degree assault, and a charge related to the gun he’s accused of using.
