Ola Salem was, by all accounts, fearless. As a teenager, she stood up to the managers of an amusement park after she was not allowed on rides because she was wearing a head scarf. She worked out at a boxing gym and was considered a fierce protector at the domestic violence shelter where she volunteered. She went skydiving.

Then Ms. Salem, 25, turned up dead .

Her body was discovered on Oct. 24 in Bloomingdale Park on Staten Island, partially covered by leaves and fully dressed, according to the police.

But her death has not been ruled a homicide, and no arrests have been made. News outlets reported that there were no signs of blunt-force trauma to the body, only marks consistent with having been dragged into the underbrush.

A spokesman for the New York Police Department, Al Baker , said there is an ongoing investigation into the death but would not comment further. The city’s medical examiner office said the cause of death had not been determined because it is awaiting results of toxicology tests, which can take weeks.
