John Littig and Lynne Rosen hosted the radio self-help program, "The Pursuit of Happiness." Now they're dead after an apparent double suicide pact. Last year they had said to "live spontaneously."

Last year, John Littig told the listeners of his WBAI radio show with partner, Lynne Rosen, that "So much about life is about impulse. It's about doing it right now."

Now Littig and Rosen have done something they can't undue and police say the couple committed double suicide as part of a pact on Monday night.

A spokesman from the medical examiner's office said on Thursday the autopsies found that both Littig, 47, and Rosen, 45, died from asphyxiation after inhaling helium.

Their bodies were only discovered Wednesday on a couch in the couple's brownstone in Brooklyn, with so called "exit bags" over their heads.

Their suicide method has come into vogue recently with the advent of of "a fast, peaceful, undetectable death" compared with the carbon dioxide. This comes according to a fire department memo prepared for paramedics.

They both wrote separate suicide notes, with Lettig's saying they were determined to die together while Rosen apologized to her family, according to police.

Besides the ambiguity of the suicide notes, police were baffled as to why a couple that gave advice on happy living would choose to cut their own lives short.

But the fact the Lettig's focused on them dying together and Rosen's was apologetic to her family, it stands to reason that Lettig may have enticed his radio partner into a suicide pact, and she followed through with him out of love.

Lynn Rosen is a clinical psychologist, and it's a wonder she didn't try and talk John Littig out of the morbid pact.

The WBAI didn't respond to a call to their offices yesterday, but the station did send out a tweet marking their deaths, writing "RIP Lynne Rosen + John Littig. Partners on the air and in life."

During one show focusing on Albert Einstein's quote, "Imagination is more powerful than knowledge," Littig trumped up the necessity of changing and stepping outside your comfort zone.

"Intuition, impulse are extraordinarily important things in life," he says. "You will not be well-served if the impulse is shut down or you think about everything too much. Sometimes you just do it."

Whether Rosen shared her partner's thoughts on the matter, via suicide, is clear now, but as more details surface many are wondering whether Rosen might have been the victim of Littig's own self-vicimization and Rosen wanted to ease his apparent suffering by also committing suicide.
