Law enforcement officials told the Buffalo News they believe the body, found in thick brush near Jorden's Hamburg home, is the 49-year-old doctor. The body had a gunshot wound, authorities said.
We believe it's him, a law enforcement source told the paper.
Local, state and federal authorities, including the U.S. Marshals and the FBI, had launched a manhunt for Jorden in the United States and Canada. Authorities described him as armed and dangerous following the shooting at the hospital on Wednesday around 8:15 a.m. The search had centered around his home for about two days.
Wisniewski, 33, whose funeral is scheduled for Saturday, was found dead in a covered passageway joining the hospital's Kidney Center and another wing of the medical center, The Miller Building, ABC News reported earlier this week. She had been identified in earlier reports as Jorden's ex-girlfriend.
A Mass will be held Saturday morning at St. Martin of Tours Roman Catholic Church in Buffalo for Wisniewski, a single mother, who was shot four times inside a stairwell at the hospital where she worked as an administrative assistant, according to the Associated Press.
The hospital campus went into lockdown shortly after the shooting.
Buffalo police, backed up by a New York State Police SWAT team, swarmed the grounds, fanning out to search for the shooter, who fled the scene.
Officials said Jorden was a decorated career soldier who graduated from the University Of Buffalo School Of Medicine in 1996, but according to officials, he had experienced emotional difficulties recently.
Jorden's ex-wife, Francisca Wellsbury, told ABC News earlier this week she was shocked by the news that her ex-husband had become a suspect in a murder.
We've lived separate lives for a long time, Wellsbury, who lives on the West Coast, said. I'm just as shocked as anyone. It's traumatic.
She declined to go into further detail, but said: This is not the person I knew. I wish he would seek help.
Jorden's military career spanned 18 years with two periods of service, earning him numerous medals and commendations, including the Army Achievement Medal, Army Commendation Medal, Meritorious Service Medal and Master Parachute Badge Scuba Diver Badge Special Forces Tab.
