GURNEE, Ill. -- An employee of Six Flags Great America has died of injuries suffered on a ride at the theme park May 29.

Jack Brouse, 52, was from Zion, Ill. He had been a ride mechanic at the amusement park for six years.

A Six Flags security report said Brouse apparently "stepped into the path of one of the cars in an attempt to get to the other side" of the tracks, and a speeding roller coaster car hit him in the head.

Brouse did not die at the scene, but was eventually taken to Froedtert Hospital in Milwaukee.

Doctors there found that Brouse had survived previous heart surgery and lung cancer.

When a lung collapsed on June 7, doctors had to put him on a ventilator, but his family told doctors he didn't want to live that way.

The family had him taken off life support June 8. He died Wednesday.

The medical examiner listed the cause of death as traumatic head injury.
