An 18-year-old man died in a motorcycle crash Friday night in southwest suburban Plainfield.

Johnson D. Ho, of Plainfield, was driving a motorcycle north near the intersection of Route 59 and Dayfield Drive about 11 p.m., according to the Will County coroner’s office.

A van traveling east entered the intersection and crashed into the motorcycle, a statement from Plainfield police said. The passengers inside the van were not injured and refused medical attention.

Ho was pronounced dead at the scene, the coroner’s office said.

Preliminary results from an autopsy performed Saturday showed Ho suffered multiple injuries from the crash, according to the coroner’s office. The autopsy did not rule on his final cause and manner of death pending further study.

Route 59 remained closed for about five hours after the crash while Plainfield Police Crash Reconstruction Unit investigated, police said.
