Prosecutors want a federal judge to bar a Canadian man convicted of stealing his dead infant brother’s identity from filing any more civil pleadings against witnesses in the case.

The government’s unusual request was made Friday in the criminal case against 58-year-old Leslie Lyle Camick, formerly of Winfield.

His criminal defense attorney didn’t immediately respond to an email seeking comment.

Jurors convicted Camick on Jan. 30 of aggravated identity theft, obstruction of justice, mail fraud and wire fraud. His sentencing is April 21.

The obstruction of justice charge stems from a separate federal civil rights lawsuit Camick filed against his former girlfriend, her company and law enforcement authorities after his indictment.

Prosecutors say Camick continues to file pleadings in his civil case containing “unfounded, frivolous and slanderous” allegations against witnesses.
