Two people were arrested Thursday morning after investigators say the gun-toting pair rushed into a home on the far Northwest Side and beat the homeowner.

The incident occurred shortly after 8 a.m. when two people knocked on the door of a home in the 10300 block of West Massingale Road, east of North Sandario Road, according to Deputy Dawn Barkman, a Pima County Sheriff's Department spokeswoman.

The owner opened the door and the pair made their way inside, she said.

They tied him up and assaulted him before leaving in a gray Toyota Tundra, Barkman said.

As deputies responded to the home, they spotted the Tundra and a chase ensued.

They headed east on West Picture Rocks Road through the Saguaro National Park monument, she said. Picture Rocks turns into North Wade Road.

At Wade and West Ina Road, deputies spiked the tires and it came to a stop just west of Interstate 10 near the Red Roof Inn hotel.

The woman who was driving the truck got out and ran but was caught a short time later, Barkman said.

The man who was in the passenger seat was taken into custody without incident but did prompt a response from the bomb squad when deputies discovered a suspicious package in his pocket.

It is unclear what is inside the package, Barkman said.

The driver, Julia Nicole Leon, 27. She was charged with domestic violence-related aggravated assault, kidnapping, armed robbery, auto theft and fleeing from law enforcement.

Her companion, Toby Ryan Putman, 32, was charged with aggravated assault, kidnapping, armed robbery and prohibited possessor of a firearm.

They were both booked in to the Pima County jail.

Investigators said Thursday that Leon had lived at the house with the victim until recently.
