Edythe Maa aka Jade Vixen Deadly Love Triangle (PHOTOS)

, the S&M dominatrix alter ego of brunette Ivy Leaguer, was kidnapped by obsessed client, after he shot her boyfriend, attorney

Ottaviano, 40, a lawyer at one of Manhattan's most prestigious law firms, Paul, Weiss, Rifkind, Wharton & Garrison, had just returned with Maa to her Philadelphia home, when Krieg, 42, shot him to death and then forced Maa into his car.

Ottaviano and Maa often attended New York City fetish parties, sometimes with him wearing lipstick, a garter belt, stockings and high heels.

Krieg, who gushed on a video on his MySpace page, "Jade Vixen - she's the greatest fetish model since Betty Page!" had been stalking Maa for months.

After gunning down Ottaviano, Krieg drove around with the dominatrix - who specializes in “sensual teasing and denial, rope bondage, sissy-slut training, dog training, tickle torture, and corporal punishments of a traditional nature” - for hours.

Maa convinced Krieg to let her go, and he dropped her off at his relatives' house in West Chester, Pa., shortly after 4 a.m. on Monday.

She immediately called police, who found Krieg and forced him to pull over in a restaurant parking lot, where he turned the gun on himself.
