Tulsa: Second defendant gets prison in dog sex case

TULSA — A man received a five-year prison term Monday for videotaping a co-defendant — who got no prison time — as she engaged in sex acts with dogs.

Donald R. Seigfried, 56, pleaded no contest in November to one count of committing a crime against nature.

Tulsa County District Judge William Kellough sentenced Seigfried to five years in prison and ordered him to spend three years on probation.

Co-defendant Diane Sue Whalen, 55, received a five-year suspended sentence and no prison time in October. She pleaded no contest in September to one felony count.

Records show Seigfried has prior felony convictions for theft and drug offenses committed more than 25 years ago. Whalen had no prior criminal record.

Attorney Jerry Truster, representing Seigfried, said if Seigfried had not had the past convictions, he would have had a possibility of serving his entire sentence on probation.

According to Whalen’s sentencing report, she was recorded on video engaged in sex acts with three dogs.

She said Seigfried "was involved in taping, directing and giving advice” to her as she performed in the videos, the report states.

Seigfried had been free on bond. He was jailed Monday.
