SYRACUSE, N.Y. -- Two years after a teenager was gunned down while walking at night along South Avenue, his killer remains free and his murder unsolved.

Syracuse police detectives are still investigating the murder of 17-year-old Dylan Cheek, who was killed May 8, 2013. Detectives, however, have not identified any suspects, Lt. Eric Carr, a department spokesman, said Tuesday.

"But we are looking for the public's assistance on this case," he said.

Cheek was walking in the 1400 block of South Avenue around 10:15 p.m. on May 8, 2013 when a dark-colored car pulled up and someone fired multiple shots from the vehicle. The car sped off. Police said Cheek, who died at Upstate University Hospital, was walking alone that night.

Two days before his murder Cheek had gotten out of jail.

Prosecutors at the time said the teen had been charged with burglary, assault and criminal possession of a weapon in connection with a stabbing. He was arraigned in city court on May 2 and held until a preliminary hearing.

When a witnesses failed to show up for the hearing, however, Cheek was released.

Detectives still aren't sure what the motive in the murder was, but police have said it appeared that Cheek was specifically targeted.

Cheek had earned his GED diploma through Syracuse Educational Opportunity Center. He left behind a 2-year-old daughter, Kiara L. Cheek.

Crime in the city of Syracuse has dropped in recent years, following a national trend. In 2014, violent crime in the city fell to its lowest level in 25 years. Homicides, however, hit record highs in 2013 and 2014.
