PHOENIX -- The Arizona Department of Public Safety says the semi-truck driver that caused a deadly crash on Interstate 17 near Bell Road Wednesday morning has been booked into jail on one count of second-degree murder.

DPS identified that driver as 54-year-old Brian Knoll, of Phoenix.

The agency identified the driver who was killed as 22-year-old Paul Troupe, of Phoenix. His Mercedes SUV burst into flames after it was rear-ended by Knoll's vehicle according to DPS.

Investigators say Knoll veered from the far right lane of northbound I-17, hitting four cars stopped for traffic congestion before slamming into the concrete median barrier and spilling his load of brick pavers into the southbound lanes.

He was given field sobriety tests on scene then hauled off in handcuffs.

DPS confirms Knoll was arrested as part of a DUI Investigation and booked into jail on one count of second-degree murder.

According to a press release issued Wednesday afternoon, additional charges could be forthcoming.

A passenger in a pickup truck that was also hit by Knoll was still hospitalized Wednesday afternoon with what investigators described as life-threatening injuries. That person's name has not been released.

The I-17 was closed for several hours as DPS investigated the crash. All lanes had reopened by about 2 p.m.
