NILES — Two Niles men were reported in fair condition Saturday at Memorial Hospital in South Bend following a head-on crash on South Third Street.

Michigan State Police in Niles identified the motorists as John Westgate, 57, of Ontario Road, and Ronald Marrs, 55, of Howard Street. A medical problem suffered by Westgate may have led to the crash, police said.

Police said Westgate was driving south on South Third near Bertrand Road shortly after 5 p.m. Friday when his car swerved into the northbound lane, passing two southbound cars stopped at a stop sign. The car, a 1995 Chevrolet Corsica, traveled off the road shoulder and hit a stop sign and mailbox, police said.

They said the car then traveled back onto the road, heading south in the northbound lane. After side-swiping two northbound vehicles, several other motorists were forced to dodge the oncoming car, police said, before it struck Marrs’ northbound 1996 Dodge Intrepid.

Niles Township firefighters had to extricate Westgate and his daughter, Kandra, 13, of Dowagiac, from their vehicle. Kandra was treated at Lakeland Hospital in Niles and John Westgate was transferred to Memorial.

Police said they were continuing to investigate the accident.
