Police in the Chicago suburb of Crystal Lake say two men have died in a small plane crash.

Crystal Lake Deputy Police Chief Gene Lowery says the plane crashed Thursday afternoon just west of the Lake in the Hills Airport, about 50 miles northwest of Chicago.

The McHenry County coroner’s office has identified the victims as 65-year-old Hugh Scott Clark of Lake Forest and 82-year-old Paul Sanfilippo of Grayslake.

The Federal Aviation Administration says it’s unclear if the plane was taking off or landing.

Crosswind may have played a role, according to authorities.
