A man charged with the violent attacks on two Billings women in their homes spent a decade in prison for similar crimes in New Mexico.
Toby Griego, 41, was charged earlier this week with 26 felonies and three misdemeanors in connection with the May 27 and July 2 home-invasion rapes and robberies of two women.
He remains under investigation for a string of four similar crimes that began in January and caused widespread fear in the Billings community when authorities announced they were looking for a serial rapist.
Griego was arrested Aug. 23 and is being held in the Yellowstone County jail on $1 million bond.
According to an article published Aug. 28 in the Santa Fe New Mexican newspaper, Griego committed similar crimes in that city, including the rape of a 16-year-old girl in 1997, followed the next year by attacks on four other women.
The newspaper reports that Kelley Hollingsworth, now 32, was raped by Griego after a high school homecoming football game in October 1997.
Now a dentist in Santa Fe, Hollingsworth has previously discussed the attack publicly, the newspaper reports, and was interviewed about the crime again this week.
Griego was working in Santa Fe as a milkman when he saw Hollingsworth putting gas in her car, followed her to a residence and abducted her from her car as she was putting on lipstick.
Griego dragged the girl to a vacant house, choked her and sexually assaulted her. He then put her in the trunk of her car, drove it around town and at one point stopped and rinsed her body off with water from a bottle.
Griego eventually stopped, opened the trunk and threatened to kill Hollingsworth if she got out of the trunk before 10 minutes had passed, the Santa Fe newspaper reports.
Several other sexual assaults were reported at about the same time, and other women had reported being assaulted by Griego, but he was not charged with any other crimes.
The following year, Griego was sentenced to 12 years in prison for aggravated burglary, robbery and two counts of auto burglary for attacks on four women.
While serving that sentence, Griego admitted in 2002 to the assault on Hollingsworth and later pleaded guilty to second-degree rape.
Griego was sentenced to a concurrent term of nine years in prison for the rape charge.
Griego was released from prison on parole in 2006 after serving eight years.
He was sent back to prison on a parole violation after he was accused of trying to take pictures up the skirts of teenage girls, was charged with resisting arrest and tampering and admitted to possessing pornography.
In 2008, Griego was released from prison. Local prosecutors have said he moved to Montana in that year.
In the two Billings rape cases, Griego is accused of breaking into the women's residences while they slept, binding them and raping them with foreign objects.
Both women were forced to their cars and driven to ATM machines to withdraw cash, and one woman was taken to a canal and forced into the water.
