QUINCY, MASS. (WHDH) - An 18-year-old man charged in connection with a shooting in Quincy that claimed the life of a Weymouth High School student last month was ordered held without bail on Tuesday, but police believe the person who pulled the trigger has fled the country.

Jaivon Harris, of Quincy, pleaded not guilty in Quincy District Court to charges of murder, armed robbery, assault and battery with a dangerous weapon, and conspiracy in connection with the death of 17-year-old Nathan Paul.

Paul was found suffering from a gunshot wound inside of a crashed car in the area of Palmer Street on Feb. 15 around 6:30 p.m., Norfolk District Attorney Michael W. Morrissey said. He was taken to a Boston trauma center, where he succumbed to his injuries.

Prosecutors said Paul was selling marijuana and THC devices when some teenagers paid with counterfeit cash. Prosecutors said teenagers saw a car come down the street and push Harris and another person into a snow bank, and that they heard two pops.

Police say Paul had a gunshot to his leg and crashed his mother’s SUV into a car and house, and internal bleeding led to his death. Police found two .40 shell cases at the initial crime scene, but did not recover guns.

Harris’ attorney said prosecutors were “throwing everything against the wall and hoping something sticks,” saying their complaint does not show Harris had a gun. State police said they do not believe Harris pulled the trigger and are searching for another juvenile who flew to Puerto Rico after the shooting.

Nathan was a Weymouth High School senior who played on the football team.

His father, Gregory, said Nathan was getting ready to turn 18 in March and trying to decide where he wanted to go to college.

“He didn’t deserve to die. He was only 17 — a kid,” Gregory Paul told 7NEWS.

Weymouth High School had set up grief counselors for students and staff following Nathan’s death.
