Norwalk police are investigating the death after a 20-year-old man.
Staff from the Norwalk Hospital Emergency Department called police around 1:30 a.m. on Sunday after an unresponsive male who was brought to the emergency room was pronounced dead.
Police identified the man as Alejando Garcia and said his friends brought him to the hospital in a private car.
Garcia was pronounced dead on arrival. His friends stayed at the hospital until police arrived and were cooperating with the investigation, police said.
An autopsy performed on Monday showed no signs of foul play and the office of the chief medical examiner is waiting on more test results to determine the cause of death.
Anyone with information about the incident is asked to call Detective Justin Bisceglie at 203-854-3181 or e-mail firstname.lastname@example.org.
