MINOT (AP) - Ward County Sheriff Vern Erck has been interviewed for a Court TV segment on Richard McNair, a convicted murderer with ties to the area who escaped from prison in Louisiana.

McNair was serving three life sentences for killing one man and wounding another at a Minot grain elevator in 1987. He escaped from a maximum-security prison in Pollock, La., on April 5. His last sighting was in Manitoba in late September or early October.

A crew from Results Unlimited, a Minot marketing and advertising company, interviewed Erck at the Ward County Jail on Wednesday for Court TV, a national cable television network.

Erck estimated that the number of nationwide shows about the case featuring his department is "close to 10."

The more exposure, the better, law enforcement authorities say.

"It's my belief that someone may be looking at him right now and not realizing who they're seeing," said Glen Belgard of the U.S. Marshals Service office in Alexandria, La.

Belgard said the agency still is investigating hundreds of leads coming in on McNair from the United States and Canada.
