PHOENIX -- Some unusually violent kidnappings occurred in the Valley this week.

Tuesday night, Phoenix police were called out to the Maryvale neighborhood after a victim escaped from his captors.

The victim, Renan Beltran-Leon, told officers that his kidnappers bound his wrists and ankles with duct tape and held him captive without food for a week in a home near 79th Avenue and Osborn Road.

When nobody paid the $100,000 ransom, his kidnappers decided to bury him in the house and brought in cement-cutting machines, police said. Beltran-Leon overheard them saying they were planning to bury him alive.

"He actually saw the suspects bringing the machinery in to cut the cement, based on what I was told," said Officer Luis Samudio, of the Phoenix Police Department. "He also heard the machine. These machines make a loud noise cutting the cement."

Beltran-Leon escaped out the bedroom window to a neighbor's house and called police.

When the kidnappers noticed he was gone, they ran out the front door and were met by police, officers said.

“That’s just horrible. People do that to each other. It's terrible," said Kevin Widener, who lives in the neighborhood.

Officers arrested Mariano Perez Gonzales and Doroteo Estrada Perez. They also said Beltran-Leon was likely involved in criminal activity as well.

On Thursday, investigators found a shotgun and a handgun at the home. The investigation is continuing.

Also this week, the SWAT team rescued another kidnapping victim from an abandoned house in south Phoenix.

“They found that he'd been bound with duct tape, beaten and been burned around his body," Sgt. Tommy Thompson, of the Phoenix Police Department.

The 31-year-old victim was hospitalized for burns to his arms and groin. Police said he was jumped in an apartment complex across town, then thrown in the back of a car and taken to the south Phoenix home.

Investigators said the captors demanded a ransom of $20,000 and two cars.

Jorge Reynoso-Ontiveros, Rafael Zamora-Osuna, and Rosendo Castrellon-Flores were arrested in connection with the kidnapping.

Police said nearly all of the suspects and victims are involved in either human or drug smuggling.

“It's a cash business these people are in. We've had ransoms for drug smugglers that have been as high as a million dollars," said Sgt. Thompson.

Phoenix Police Department’s Home Invasion and Kidnapping Enforcement Squad has tallied more than 200 cases so far this year, according to Sgt. Thompson.
