A 19-year-old Ansonia man died after a one-car crash on Route 34 in east Derby Friday evening.

Officials did not release the man's name Friday, but social media identified him as Josiah Bazil, a 2014 Ansonia High School graduate who played on the school's basketball team.

His friends used Twitter and Facebook Friday night and Saturday morning to express their grief and offer condolences to the young man's family. Some of those messages are posted at the end of this article.

Bazil can be seen on the left in this photo from the Rep-Am and in this photo from last year's graduation ceremony at Ansonia High School.

Bazil was a father. His social media feed has photos of him doting with a wide grin over his baby, born last year.

Although the investigation is ongoing, it is thought Bazil had a medical issue of some kind in the moments before the crash.

The initial medical dispatch at 5:42 p.m. reported a person was thought to be having a seizure.

"The Derby Police Department is investigating and will await further information from the Office of the Medical Examiner," Lt. Justin Stanko said in a prepared statement.

Police, the fire department and emergency medical personnel responded to a report of a one-car accident on Route 34 east near Mount Saint Peter Cemetery.
