Less than three hours after a dead man was found floating in a lake in a North Bergen park at 10:15 a.m. Christmas morning, another dead man was discovered by the same park's tennis courts with a "ligature" around his neck, according to a press release Wednesday night by the Hudson County Prosecutor's Office.

The two deaths in the James J. Braddock North Hudson County Park in North Bergen "appear to be unrelated at this time," according to the release.

In the first incident, two joggers found the dead man floating in the park's lake at around 10:15 a.m., officials said. Investigators said he appeared to be in his mid-30s with no signs of trauma to his body.

The circumstances of his death are under investigation, officials said.

Passersby found the second dead man, lifeless and with a "ligature" around his neck, on the ground by the tennis courts at around 1 p.m., officials said.

Detectives believe the second death "may be self-inflicted and a suicide," but are waiting on a final determination from the Medical Examiner's Office following an autopsy.

The HCPO is handling the investigation of the first death, while the Hudson County Sheriff's Office is handling the investigation of the second death with the assistance of the HCPO, the release said.

The HCPO declined to release further information about the two deaths.

Jersey Journal staff writer Chinedum Emelumba contributed to this report.

Correction: This article stated earlier that the HCSO is leading the investigation of both of the deaths, but has now been corrected to reflect the fact that the HCPO is leading the investigation of the first death and the HCSO is leading the investigation of the second death with the assistance of the HCPO.
