YAPHANK, N.Y. -- Police and federal agents Wednesday searched the home of a policeman and his wife who sources said might be linked in a love triangle to the car bombing that killed an undercover narcotics detective.
An attorney for the suspected officer denied he had anything to do with the slaying.
Suffolk County Detective Dennis Wustenhoff was killed last Thursday by a bomb rigged under his car. Investigators have said the leading motive was 'revenge for a drug bust.'
Authorities Wednesday would not comment officially on any investigation into reports that Wustenhoff may have been involved in a romance with the wife of Nassau County police officer Robert Horan, assigned to the Emergency Service.
His wife, Nancy Lanon, is a secretary at the federal Drug Enforcement Administration in Suffolk County.
The couple left for vacation in Cooperstown, in upstate New York, shortly after Wustenhoff was killed by the bomb rigged to his county-owned Cadillac, parked in front of his North Patchogue home, sources said.
Although police sources said Horan was being questioned, his attorney, Stephen Scaring, said his client 'is not in police custody, is not with police and is not speaking to police.'
'Bob Horan denies any involvement in the death of Detective Wustenhoff,' Scaring said.
Scaring, once chief of the Nassau County district attorney's Homicide Bureau, would not say where Horan and his wife were, but said, 'He goes on with his life. He is a free man.'
Horan has been temporarily reassigned from the emergency services division to the records bureau at the overnight detention area in police headquarters in Mineola because of the investigation, Nassau County police spokesman Detective Richard Snizek said.
The temporary reassignment takes affect at 12:01 a.m. Saturday, two days before Horan is scheduled to return from a one week's vacation.
Wednesday morning, agents of the federal Alcohol, Tobacco and Firearms Agency and Suffolk homicide detectives could be seen inside the Horan's modest, two-story Dutch colonial home in Bethpage.
Outside, Nassau County police provided security and kept the curious off the property.
Earlier Wednesday, Suffolk Police Commissioner Daniel Guido told reporters that none of the reports linking the Horans to the investigation was leaked 'from this police department.'
'We are not making any progress reports. We have not misled anyone. This department has continously said that from the beginning we have been working on a number of theories.'
Guido acknowledged, however, 'We have been investigating his (Wustenhoff's) personal life, as well as other matters.'
Earlier, Guido inferentially acknowledged the spread of reports suggesting a love triangle by asking the public not to jump to conclusions and 'inflict a second major tragedy on the grieving Wustenhoff family.'
'Certain news media reports have had the effect, without intending to do so, of distracting us from the accomplishments of Detective Dennis Wustenhoff, thereby diminishing in the eyes of some his stature as an authentic hero, which he is beyond any question,' Guido said.
Horan's neighbors said police questioned them Tuesday and searched Horan's with dogs.
They said the couple has been married about eight or nine years and lived in Bethpage about eight years. They have two children, Erin, 6, and Megan, 2. Horan also has a daughter, Kelly, 15, by a previous marriage.
Horan's father, Walter, a former Nassau County police officer, lives nearby.
Neighbor John Corso described Horan as 'the greatest guy in the world' and said Horan and his wife appeared to be 'the happiest couple around.'
Another neighbor, Steven Braccia, 22, described them as 'wonderful people' and said they gave an annual Fourth of July party.
More than 5,000 officers from 47 separate police departments throughout metropolitan New York and the Northeast attended funeral services Monday for the father of three in a Patchogue funeral home.
