Police investigating the death of a former Pentagon aide said this morning he was last seen on a surveillance video in downtown Wilmington at 8:30 p.m. Thursday, about 14 hours before his body was found in a Wilmington landfill.
Newark police, who have classified the death of John Parsons Wheeler 3d as a homicide, said the surveillance video showed him inside the Nemours Building at 10th and Orange Streets and that he appeared "confused."
Police also said Wheeler was approached inside the building earlier in the day by several individuals who offered assistance to him, which he declined.
On Tuesday, police discovered evidence that Wheeler may have been involved in an attempted arson days before his death, a law enforcement source told The Inquirer.
The source emphasized that the evidence does not shed light on Wheeler's death, but it has helped detectives understand his state of mind before he disappeared.
Police found evidence linking Wheeler to devices planted at the New Castle home of a neighbor with whom he had been feuding, said the source, who is close to the investigation. The feud was over the size of the neighbor's house, which was under construction across the street from the residence Wheeler shared with his wife, Katherine Klyce, in the city's historic district.
Wheeler was found dead in the Cherry Island Landfill about 10 a.m. on Friday, in refuse that came from trash bins in one of 10 possible locations in Newark, Del. Police said they have been trying to retrace his movements between Dec. 28, when he left his office outside Washington, to when his body was discovered.
The case has drawn national attention - Newark police received roughly 70 media calls Tuesday - because Wheeler, 66, lived such a distinguished public life.
A Vietnam veteran who became a driving force behind the controversial memorial on the National Mall, Wheeler worked on nuclear, chemical, and cyber issues at the Pentagon. He was the first chief executive officer of Mothers Against Drunk Driving, a secretary of the Securities and Exchange Commission, and a tireless advocate for veterans.
On Tuesday, police said detectives verified that Wheeler had been seen Thursday near 10th and Orange Streets - close to the Hotel du Pont - but a police spokesman declined to say how this was confirmed. An executive at the nearby DuPont Corp. headquarters, which employs outdoor surveillance cameras, said that the company had "cooperated" with the police but declined to elaborate.
Police say they have no suspects and have released few details about the slaying - in part because they themselves have so many unanswered questions, including where the killing took place.
"We're still trying to [find] the crime scene," said Newark police spokesman Mark A. Farrall. "We're working a lot of leads."
Farrall has said that Wheeler died shortly before his body was discovered Friday, but has not described how Wheeler died - whether, for example, his death was caused by gunshot, bludgeoning, or some other violent act.
An official cause of death will not be released until "toxicology reports and other forensic studies" are completed, said Carl Kanefsky, a spokesman for the medical examiner.
"It's quite a mystery, and the length of time it's taking to solve it makes it more intriguing," said Bayard Marin, a lawyer who represented Wheeler in the dispute over a neighbor's plans to build a large house in New Castle's historic district.
The Wheelers tried to halt those plans in court, contending the house was too big for the neighborhood.
The incendiary devices were placed at the neighbor's home last week, police said, days before Wheeler returned from his part-time consulting job for the defense contractor Mitre Corp., located in McLean, Va., outside Washington.
Marin said he did not know if the devices or Wheeler's death had any connection to the building dispute, but he said tempers in the court case never rose to acrimonious levels.
Marin said he was interviewed by police Tuesday for 45 minutes, but he would not say what detectives asked. "I guess they are just gathering all the miscellaneous facts and hoping to tie them together to find something they can make of it," he said.
Meanwhile, in Manhattan, police on Tuesday searched the condominium that Wheeler and his wife had shared in a brick building on 124th Street for at least three years, the Associated Press reported.
Wheeler's wife, Katherine Klyce, who operates an international textile company with ties to New York and Cambodia, is unavailable for comment, according to a family statement.
The FBI on Tuesday offered "technical assistance" to the police, said FBI spokesman Rich Wolf. He declined to elaborate, but in FBI parlance, the term "technical assistance" typically refers to forensic assistance. It does not mean the FBI is conducting a full investigation.
In Delaware, authorities returned to the Cherry Island Landfill on Tuesday but kept reporters at bay.
Farrall, the police spokesman, said only, "We're looking for anything that might be of evidentiary value."
Sanitation crews used an alternative site at Cherry Island on Tuesday, so that police could comb the area where the body was found without interruption, said F. Michael Parkowski, a spokesman for the Delaware Solid Waste Authority.
Parkowski said it was not surprising that workers had discovered Wheeler's body in time to retrieve it from the landfill. He said truck drivers as well as workers known as "spotters" are trained to watch garbage for suspicious items as it is dumped at the site.
The defense contractor that had employed Wheeler part time since 2009 issued a short statement Tuesday. "At this time our thoughts are with his family," Mitre said.
The statement said Wheeler's work for Mitre consisted of "providing part-time support to outreach activities aimed at promoting discussions among government, industry, and academia on cyber defense topics." Company spokeswoman Jennifer J. Sherman declined to further explain his duties.
The cause of Wheeler's death - if it has been determined - is likely driving the focus of the investigation, said Michael Carbonell, a former FBI agent who supervised the agency's violent-crime squad in Philadelphia.
"If he died by blunt-force trauma or was shot, it tells us it was probably a random street crime, but if he's strangled, that's different," said Carbonell, who emphasized that he was merely speculating on the basis of his decades with the FBI.
The biggest publicly known clue, Carbonell said, is that the killer or killers apparently tried to hide Wheeler's corpse by placing it in a trash bin.
"Guys who rob and shoot a guy do that and run," Carbonell said. "Somebody went to some extra effort to dispose of the body."
