DPS: Joseph Ryan O'Conner arrested in deadly Interstate 17 crash

PHOENIX - The Arizona Department of Public Safety has made an arrest following Monday's deadly crash on Interstate 17 in Phoenix.

DPS spokesman Carrick Cook said that 27-year-old Joseph Ryan O'Conner was arrested at 11:40 a.m. Thursday.

A motorcyclist was killed in the multi-vehicle accident that happened on I-17 near Thomas Road around 3 p.m. on Monday.

A flatbed truck carrying compressed gas cylinders, allegedly driven by O'Conner, was being followed by an SUV, motorcycle and big rig.

Tony Mure with the Phoenix Fire Department said cylinders began falling out of the back of the flatbed truck, which was traveling southbound.

As the cylinders began falling, the SUV and motorcyclist tried to swerve out of the way.

The driver of the big rig slammed on the brakes but ran over the motorcycle and its rider.

The big rig then hit the SUV carrying two adults and four children. A woman and child were taken to the hospital.

The motorcyclist, 27-year-old Steven Matthew Daniels of Prescott Valley, was taken to the hospital where he later died from his injuries.

The crash also set off fiery explosions.

There is no word yet on what charges O'Conner is facing.
