Authorities say a 38-year-old man has been arrested and is being held without bail on charges of raping and sexually abusing a girl under the age of 12 near Salem.
Keizer police detectives began investigating Mendez-Alcarez in March after receiving information from the Oregon Department of Human Services.
Keizer police Lt. Chris Nelson says the department finished its investigation in July and they are unaware of any other victims.
According to court records, the alleged rape and abuse took place between January 2010 and January 2011.
