William Robert Gustafik of San Ramon described himself in an online profile as a chiropractor and professional poker player who planned to compete "with his beautiful wife at his side."

On Friday, his wife, Jill Rockcastle, 49, allegedly stabbed Gustafik to death inside an upscale, high-rise Las Vegas condominium just off the famed Strip.

The slaying is believed to have resulted from a domestic dispute, Las Vegas police Officer Jose Montoya, a department spokesman, said Tuesday.

About 7:30 p.m. Friday, Las Vegas police received a call about a dead man inside the 32-floor Panorama Towers complex on South Dean Martin Drive, located west of the Bellagio Hotel and Casino and the Las Vegas Strip.

Officers found Gustafik's body on the floor of the master bedroom on the 23rd floor of the complex where Pamela Anderson, Leonardo DiCaprio and Tobey Maguire reportedly own units, authorities said.

A knife believed to have been used in the slaying was found in the "trash area" of the complex, Las Vegas homicide Lt. Lew Roberts said.

Then, about noon Monday, San Luis Obispo police — on a tip from Las Vegas officers — responded to the Petit Soleil Bed and Breakfast on Monterey Street and found Rockcastle unconscious, authorities said.

Hospitalized with a breathing tube, she had not been interviewed as of Tuesday because of her medical condition, said Roberts, who declined to elaborate. Roberts said he didn't know what led Rockcastle to travel to San Luis Obispo.

Gustafik, 44, described himself in the online posting as a devoted husband and loving father of a 9-year-old girl. He said he has won $165,597 and became a professional poker player at the World Series of Poker in 2005. His nickname in the poker-playing world was "the Manipulator."

"Being a chiropractor by profession, I plan to go from cracking backs to cracking the stakes of the best pro," Gustafik wrote. "Nothing can stop me. When not at the table or online playing, my family is my dedication."

He owned a chiropractic office in Hayward.
