The body was identified as Roosevelt Rene, 25, a Jenkins family friend who had been living at the house, according to the Bergen County Prosecutor’s Office.
The office announced that William Jenkins was in custody, adding that the investigation is ongoing and the defendant is presumed innocent. Sources told ESPN that Jenkins was in Geneva, New York, on a parole violation and was initially held in Ontario County, pending extradition to New Jersey.
Janoris Jenkins was not at home when the body was discovered and has been in Florida since the completion of Giants minicamp two weeks ago, sources said. Jenkins has been advised by attorneys to remain in Florida, sources said.
The Giants said that they “are aware of and monitoring the situation.”
