POYNETTE, WI—Foul play is suspected in the death of an accounts receivable supervisor for a regional office-supply company, sheriff's deputies reported Tuesday.

Herbert F. Kornfeld, 34, was an alleged accounting gang leader considered by law enforcement to be a key player in a series of ongoing office worker turf wars. He was found dead Monday morning in the third-floor copy room of Midstate Office Supply, his employer of 12 years.

"We believe the victim was assaulted after hours Friday by an unknown individual or individuals," a Columbia County sheriff's departmaent spokesman said. "Though autopsy results are still pending, we believe the victim suffered fatal head trauma after his face was immobilized against the glass of a photocopier and repeatedly struck with the machine's cover."

 Midstate Office Supply vice-president Howard Dinwiddie is expected this week to name accounts receivable assistant Irving Weinbaum, 23, as Kornfeld's successor.
