Authorities have released the name of an Iowa man who was killed in a car crash after a string of burglaries and vehicle thefts Monday.

But they still have not determined what motivated the man to break into at least two homes and steal at least five vehicles.

Authorities say he died in the crash of one of those vehicles.

The Missouri State Highway Patrol reports Randy Hartline, 27, of Council Bluffs, Iowa was killed in a head-on collision on Missouri Route-92 just before three p.m.

Investigators believe Hartline stole a car in Council Bluffs, two in St Joseph, and two in the Platte City area.

The crash on Route-92 also claimed the life of another driver. Traffic investigators believe Antwinette Holtsclaw, 54, was trying to pass another motorist when Hartline crested a hill in oncoming traffic. Hartline lost control of the stolen 2003 Buick two-tenths of a mile west of Ode Road, and crashed into Holtsclaw’s KIA.
