A Florida teen was arrested on Wednesday, a day after he allegedly shot and killed a 15-year-old girl at his apartment.

Thalys Olivera, 17, was charged with manslaughter with a deadly weapon in the death of Arya Gray. WPLG reported that Gray was at Olivera’s Miami apartment with her sister and a group of friends when she was killed.

Police said they interviewed witnesses who claimed that Olivera was “recklessly brandishing” a Glock 43 gun while inside the apartment. Witnesses reportedly told Olivera to put the gun away, which he briefly did before allegedly brandishing the gun again and pointing it at Gray’s head. Witnesses said he then put his finger on the trigger and fired a single round which struck Gray in the head, according to WPLG reported.

Police said Olivera admitted to “playing” with the gun and pulling the trigger. He allegedly recounted seeing a flash that struck Gray.

Olivera appeared in juvenile court on Wednesday. He’s due back in court on June 2.
