A Colorado inmate suspected of being the "Ether Man" serial rapist in a number of states is expected to plead guilty to a rape in Albuquerque.
Howard Bruce is scheduled to appear in an Albuquerque court Tuesday and is suspected of committing at least 12 rapes in New Mexico in the 1990s.
Bruce is serving a 64-year sentence for attempting to blow up a police officer's home. He is accused of being the Ether Man, who was known for using chemicals to subdue dozens of rape victims in Colorado, New Mexico and Texas.
He has also been linked to rapes in Oklahoma.
It was unclear which attorney in New Mexico was representing Bruce.
