The 18-year-old who was critically injured after his car struck a tree in Manchester early Wednesday has died, according to police.
Police said Safwaan Dalal was driving eastbound on Vernon Street when he veered off the road and up a car, then slammed into a tree on the 200 block.
Dalal was a recent graduate of Manchester High School, according to the school's student newspaper. Counselors will be at the school on Monday to offer support to students.
Investigators are still probing the cause of the crash but said speed may have been a factor.
According to the fire department, Dalal was trapped inside the car and was unconscious and unresponsive at the scene. Firefighters had to extricate him and gave him medical treatment on the scene.
Dalal was taken to Manchester Hospital, then airlifted via LifeStar for Hartford Hospital.
Anyone with information is urged to call Manchester police Officer Aaron Calkins at 860-645-5560.
