NEW YORK — NBC Universal has “amicably resolved” a $105-million lawsuit filed by a woman whose brother committed suicide during a taping of its controversial “Dateline NBC” series “To Catch a Predator,” both parties said today.

Bruce Baron, an attorney for Patricia Conradt, told The Times in an interview today that “the matter has been amicably resolved to the satisfaction of both parties.”

Conradt’s brother, Louis William Conradt Jr., a 56-year-old assistant county prosecutor in a Dallas suburb, shot himself in November 2006 when officers showed up at his house as part of a pedophilia sting arranged by “Dateline.”

Patricia Conradt sued NBC last July, claiming that the network interfered with police duties and then failed to protect her brother's safety.

When asked today about the status of the suit, NBC News spokeswoman Jenny Tartikoff echoed Baron, saying “the matter has been amicably resolved.”

Both sides declined to comment on when they came to agreement or the terms of the resolution. A sealed document regarding the suit was filed with the court June 3, but the case remains open, according a spokesman for the New York Southern District Court.

The resolution of the lawsuit caps a controversial chapter for “Dateline,” which drew both ratings bonanzas and sharp critiques for its “To Catch a Predator” investigations. In the segments, which NBC began airing in 2004, the newsmagazine worked with an Internet watchdog group called Perverted Justice to contact men online who were seeking to meet underage children for sex, then lure them to a house, where they were confronted on camera. Police waiting outside then arrested the men.

Media ethicists objected to the deception used in the investigation, as well as NBC’s close relationship with law enforcement agencies in the jurisdictions where it set up stings.
