Prosecutors brought two new charges Tuesday against a man accused of committing a string of rapes and robberies in Billings earlier this year, making a total of 40 charges against the man.
Toby Eugene Griego, 41, appeared by video from the county jail before District Judge Russell Fagg and entered pleas of not guilty to all 40 charges in an amended complaint.
The defendant stood silently by his public defender as a prosecutor spent several minutes reading through all the charges.
If convicted of any of the rape charges, Griego would face a mandatory life sentence without the possibility of parole because of a prior sexual offense conviction in New Mexico, court records say.
The two new charges, aggravated kidnapping and attempted sexual intercourse without consent, are related to an attempted rape in April, said Juli Pierce, deputy chief attorney for Yellowstone County.
The April incident involved one of at least six victims investigators have linked to Griego. On the morning of April 25, Griego entered a West End home, tied up a young woman and tried to rape her, court records say.
The woman fought Griego, freed herself and managed to call 911 as the man ran away, the documents state.
Thirty-seven of the charges against Griego are felonies and three are misdemeanors, according to court documents.
Fagg maintained Griego's bond at $1 million. Trial has been set for early January 2014.
The charges against Griego stem from a string of home-invasion rapes, an attempted rape and robberies that took place between the end of January and first week of July.
In each case, Griego is accused of entering the residence of a young woman as she was sleeping. The women were bound, beaten and raped with foreign objects.
Two of the victims were taken to ATMs to withdraw money, court documents say. All three rape victims said their attacker forced them to bathe after the assaults.
Prosecutors said Griego, a registered sex offender for a 1997 rape in New Mexico who moved to Billings five years ago, stalked the victims before the attacks.
Griego remains a suspect in at least two other similar attempted rapes in Billings, but he hasn’t been charged in those investigations.
The felony charges filed against Griego include 10 counts of sexual intercourse without consent, one count of attempted sexual intercourse without consent, six counts of robbery, four counts of aggravated kidnapping, two counts of aggravated assault, eight counts of surreptitious visual observation or recording, three counts of drug possession, two counts of intimidation, and one count of assault with a weapon.
Griego is also charged with two counts of misdemeanor surreptitious visual observation or recording and one misdemeanor count of drug possession.
Prosecutors say that Griego took cellphone pictures of the victims and possessed numerous prescription medications when he was arrested on Aug. 23 at his residence.
