A man was taken into custody this weekend in connection with four “brutal” murders that shook communities in the Reno, Nevada, area, officials said.

Wilbur Ernesto Martinez-Guzman, 19, was apprehended Saturday, Washoe County Sheriff Darin Balaam said at a joint news conference Sunday.

Martinez-Guzman “was likely in the United States illegally and was detainable,” immigration officers verified Saturday afternoon, said Carson City Sheriff Ken Furlong.

Martinez-Guzman, who has been living in Carson City for about a year, is being held in the Carson City Detention Facility on immigration charges and charges related to possession of stolen property, Balaam said.

Investigators will be seeking an arrest warrant for the murders in the coming days, Washoe County District Attorney Chris Hicks said at the news conference.
