Kristjan Ndoj, who was found bleeding, shot twice in the driveway, was passed away at the hospital Thursday morning.
Police responded to Agawam Trail shortly before 9 p.m. Saturday and discovered the teen, who was rushed to Bridgeport Hospital.
Ndoj attended Shelton High School, where extra police officers and a crisis team patrolled to help students.
Authorities say the boy doesn't live at the home where he was found. Police are focusing on a wooded area surrounding the house.
State and local investigators recreated the shooting scene Monday, but police have offered no clues on a possible motive.
"He went with a friend to visit another group of friends," Shelton police Lieutenant Robert Kozlowsky said. "That is why he was on the street that night."
The victim was a sophomore at the high school, and friends and area residents were taken aback by the news.
"It's very shocking for this neighborhood," neighbor Nick Mazurok said. "It's very, very quiet. You don't see many cars come in and out, and every car you do see is your neighbor's. It's just a quiet, nice, peaceful neighborhood."
School administrators quickly reacted.
"I requested extra security, because that just sets in mind to students, staff and parents that we want to ensure a very safe environment at the high school," Headmaster Beth Smith said.
Police recovered evidence at the shooting scene but wouldn't say specifically what investigators found, saying they are still trying to determine where the shot was fired from.
The investigation is ongoing at this time. Anyone with any information is asked to call the Shelton Police Department at (203) 924-1544. Calls may be confidential.
