EUGENE — An Oregon man wanted on a warrant for failing to register as a sex offender got a new birth certificate and ID by telling a Eugene judge a story straight out of the counterculture the city is known for:

“Winter Rain Waters” was born Christmas Day of 1987 in a converted bus on “The Rainbow Farm” to parents “Misty Summer Rain” and “William Waters,” who never got around to registering the birth.

But, authorities say, Michael Allen Snow was tripped up by 21st-century technology: He applied to the state for an identification card as “Winter Rain Waters,” and the driver’s license agency ran his image through facial recognition software.

The image appeared to match one on a driver’s license issued to Snow, and investigators for the Social Security Administration were tipped off, the Eugene Register-Guard reported Wednesday.

Snow, 27, pleaded not guilty last week to federal charges of making false statements, mail fraud and failure to register as a sex offender.

Willy Gibson Whitebird, a PeaceHealth Medical Group nurse who also has worked on her own as a midwife, pleaded not guilty Tuesday to mail fraud and mail fraud conspiracy.

Snow and Whitebird are scheduled for trial Aug. 15.

Yamhill County records show Snow pleaded guilty and was convicted in 2001 of sexual intercourse “by forcible compulsion” with a victim younger than 16 in 1999, when he was five months shy of his 16th birthday. He served more than eight years.

In February 2011, when a warrant was out for Snow for failing to register, Snow and Whitebird persuaded Lane County Circuit Court Judge Mustafa Kasubhai to order a delayed birth certificate for a Winter Rain Waters, according to a search warrant affidavit in the case.

In a statement for that proceeding, Whitebird said she began prenatal midwifery care for “Misty Summer Rain” in the summer of 1987, attended the birth of “Winter Rain Waters” and remained in touch with his family for 12 years, when they moved.

“He wants to become a Naturopathic doctor and needs to enroll in school. He said he would also like to drive a car and register to vote,” Whitebird’s statement said.

Whitebird gave Kasubhai what she said were original birthing records, prenatal records and a birth announcement documenting the unregistered delivery.

The documents were created with more sophisticated software than was available in 1987, according to a search warrant affidavit from Dale Boring, a special agent with the inspector general’s office of the Social Security Administration.
