(NEW YORK) — Anna Kepner, a teenager who was found dead on a Carnival Horizon cruise ship this month, died by asphyxiation resulting from a bar hold — an arm across the neck — a source briefed on the investigation told ABC News on Friday.

Investigators also found two bruises on the side of her neck, the source said.

The FBI has continued to decline to comment, citing the ongoing investigation. The Miami-Dade Medical Examiner’s Office declined to comment Friday.

According to the source, the preliminary information indicates there were no signs of sexual assault and there did not appear to be drugs or alcohol in Kepner’s system. Autopsy and toxicology reports that could confirm those details have not been completed.
