The type of injuries regarding the occupants of the Toyota are not known at this time.

The crash closed portion of Grand Avenue for hours, leaving some motorists stranded.

Sigler, according to investigators, was arrested at the scene, but he later complained of a possible heart attack, and was taken to Banner Thunderbird Medical Center.

Sigler reportedly displayed erratic behavior while at the hospital and a toxicology report showed a presumptive positive for methamphetamine in Sigler's urine. Blood and drug tests for Sigler are still pending.

Investigators say Sigler was booked into jail upon being released from the hospital. He is accused of manslaughter and drug charges. He is being held on a $500,000 bond.
