The man accused of murdering a teenager in Cohoes is arraigned in Albany County Court.

Thomas Slivienski, 22, of Watervliet has been charged with one count of second-degree murder in the shooting death of 17-year-old Johni Dunia, as well as one count of criminal posession with a weapon. He pleaded not guilty on Friday to a grand jury. 

Police would not comment on motive but said the two individuals knew each other and were alone at the time of the shooting.

Last week the Cohoes Police Department identified Dunia as the victim of Friday night’s shooting. Spectrum News spoke with Dunia's mother, who fled violence in Congo, and his brother. You can read that here.

Since that interview, Dunia's brother, Bonfils, has remained vocal in the case. You can read that here.

Police were notified of the shooting on Friday. An individual working at a nearby convenience store told Spectrum News teens burst into the shop, saying their friend had been shot.

Police previously stated someone encountered Dunia around 10 p.m. on Friday, and called 911 from a nearby store. Firefighters and EMS responded, but police say the victim was pronounced dead.

The Cohoes school district told Spectrum News it had grief counselors on hand for any student that needed to speak with someone. The district said Dunia was a former student before switching to Albany High School where he was a junior. 

Police said the bike path trail has brought some concerns in the area. They said it was not well lit, and people should be aware of their surroundings when walking there at night. However, there has only been one other murder on that trail, which occurred in 1984. 

There is a GoFundMe for the family of Dunia which can be accessed here. 

Slivienski will be back in court for a pre-trial conference on December 14.
