Oregon father Jordan Criado suspected of slaughtering four children and his wife, then burning down house

An Oregon man is suspected of brutally stabbing his wife and four children to death before setting fire to their house on Monday.

The horror unfolded around 9:30 a.m. when fire crews responded to the blaze, which was reported by neighbors.

Tabasha Paige-Criado 30, and her three sons, ages, 5, 6, and 7, and her 2-year-old daughter were pulled from their Medford, one-story home. Rescuers soon realized that they weren’t dealing with just smoke inhalation, but stab wounds as well.

Neighbors described the scene as chaotic as they watched firefighters using CPR to revive the family members as they lay on the lawn in their front home. All five were taken to the hospital, where they were pronounced dead.

"The front yard looked like it was a plane crash or something, the people working on those folks," said Medford police Chief Tim George.

"There were some heroic efforts on the part of police and fire personnel. My understanding is they were actually able to get a pulse on two of those children at the scene, but they eventually succumbed."

The woman's husband, Jordan Adam Criado, 51, suffered smoke inhalation but is expected to survive. Authorities said they believe he killed his family but did not immediately charge him.

A motive was unclear.

Before the fire began, Criado called cops to report his wife was missing, the Medford Mail Tribune reported.

Officers found the woman a few blocks away at a convenience store and escorted her home.

"They both met and conversed," George said of the couple. "What happened between 7:30 and 9:30 in roughly a two-hour time span is what we are trying to figure out right now."
