Knife Fight Or Murder/Suicide?

"CHICAGO, IL - A South Side husband and wife found stabbed to death in their apartment Monday afternoon probably killed each other or perhaps was a case of murder-suicide, police said this morning.

"Mario Zavala, 46, and his wife, Krystal, 22, had a `volatile relationship` and had recently gotten back together, said Police Officer Laura Kubiak, a department spokeswoman.

"Police do not believe that a third person was responsible for their deaths but will wait for the results of an autopsy to make a final determination, she said. Police currently are treating the case not as a murder but as a death investigation, she added.

"There were no signs of forced entry into their apartment in the 5700 block of South Albany Avenue in the Gage Park neighborhood, Kubiak said. A knife was found at the scene.

"Each sustained multiple stab wounds, she said, adding, `We think it's a case of mutual combatants.`

"Mario Zavala was sentenced in 1987 to 33 years for murder but has a clean record since then. Kubiak said he served 20 years of that sentence. His wife had a minor arrest record for retail theft."
