NEW YORK (CBSNewYork) -- The 18-year-old charged with shooting and killing his mother at their Staten Island home is due in court Friday.

Adnan Pelinkovic faces charges including murder, attempted murder and criminal possession of a weapon.

Investigators said it started when Pelinkovic got into a dispute with his parents on Oct. 9 at their home in the New Dorp section.

According to the Staten Island district attorney's criminal complaint, he allegedly told a detective "I shot at my dad" and "I did try to kill them," CBS2's Lisa Rozner reported.

Police said officers found Minire Pelinkovic, 51, with a severe chest injury from being shot. She was taken to the hospital and pronounced dead.

The teen's father, identified as Enver Pelinkovic, 54, was found with a cut on his chest, but he refused medical attention, according to police.
