(CBS/AP) ONTARIO, Calif. - Fifty-one-year-old Carmen Montenegro was arrested for investigation of murder late Sunday after she was found pushing a trash can with body parts inside, according to police in California.
Montenegro, of San Bernardino, was arrested after residents in an Ontario neighborhood saw her with the trash can containing the incomplete set of human remains.
Investigators spent Monday excavating the property outside the home where the body is believed to have come from.
They found what may be body fluids in part of the yard, Detective Jeff Crittenden said.
"We have to wait for analysis to see if what we located is a match to the body itself," he said.
The home, which is about 200 yards from where Montenegro was spotted pushing the can, is owned by a relative of hers, Crittenden said.
He said police were looking into the possibility that the victim, who has not been identified, had been killed at the house, but he noted that the victim's body may have been taken to the house after being killed elsewhere.
