Self-Help Radio Host Couple Commit Suicide Together in Brooklyn

They were the ones who needed help.

A Brooklyn couple famous for hosting a self-help radio show committed suicide by suffocating themselves with plastic bags in Park Slope, police sources and witnesses said.

Psychotherapist Lynne Rosen, 46, and her motivational speaker husband John Littig, 48 -- who appeared on WBAI-FM's "The Pursuit of Happiness" -- were found dead in the living room of their President Street and Eighth Avenue apartment, sources said.

On the monthly show, the couple offered callers advice on how to live a happier life, sometimes tossing in inspirational quotes from Albert Einstein and Eleanor Roosevelt.

Neighbors living on the couple’s quiet brownstone-lined street called news of the double suicide sad -- and painfully ironic.

"Everyone is shocked... Everyone is wondering why," said one neighbor.

"That's really distressing that they were life coaches, handing out advice to people," she added.

Another neighbor noted the couple, who had been together 20 years, was very private.

"John was a very nice person. Lynne kept to herself… She was always putting on a lot of weight and taking it off," the neighbor said.

Littig was also a drummer who used the performance name "Jadex." The pair was sometimes spotted on the tree-lined street walking their dog.

At one point, on the radio show, Rosen encouraged her fans to fight depression with a positive attitude.

"Push yourself when there's nothing left to go on," she said."Remember, positivity is precious."

The couple was found dead on Monday morning.
