Man suspected of 11 rapes arrested in Colorado
ALBUQUERQUE, N.M. - Authorities say a man arrested in Colorado is suspected of raping 11 women in New Mexico and Texas over a 15-year span and, more recently, trying to kill a Colorado police officer.

Authorities in Albuquerque and Pueblo, Colo., are checking to see if 47-year-old Robert Howard Bruce of Pueblo might have been involved in other unsolved crimes.

Albuquerque Police Department spokesman John Walsh says Bruce was tied to the Albuquerque rapes - which go back as far as 1991 - after his DNA matched one case.

Walsh says police think Bruce may have committed crimes from 1991 to 2000 in Albuquerque and a 2006 rape in Austin, Texas.

The Pueblo County Sheriff's Department in Colorado arrested Bruce on Oct. 6 after a police officer found a 30-pound propane tank rigged to pump gas into his home.
